#14834: Executable have problems with DWARF debug information -------------------------------------+------------------------------------- Reporter: varosi | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 (Debugging) | Keywords: | Operating System: Windows Architecture: x86_64 | Type of failure: Debugging (amd64) | information is incorrect Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- We're compiling production code with GHC 8.2.2 under Windows 10 (i.e. Mingw64). A crash occured during one of our FFI bindings and we wanted to use latest GHC debugging functionallity to find the problem faster. We used a tool cv2pdb to convert DWARF information into PDB, but we hit a crash with the tool - [https://github.com/rainers/cv2pdb/issues/23] In response, the tool author brought us back a output of a problem in objdump tool over our executable: {{{ c:\tmp\cv\crash>C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe -W crash.exe >objdump C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: Encoded value extends past end of section C:\l\d\GDC-2.068\bin\x86_64-unknown-linux-gnu-objdump.exe: Warning: There is a hole [0x682a - 0x6867] in .debug_loc section. }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14834 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
