#10375: arm: ghci hits an illegal instruction -------------------------------------+--------------------------------- Reporter: erikd | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.10.2 Component: GHCi | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: arm Type of failure: GHCi crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+--------------------------------- Comment (by erikd): By hacking `configure.ac` I managed to build GHC with `-fsanitize=address` passed to GCC. Absolutely, positively, 100% certain that something is wrong: {{{ $ inplace/bin/ghc-stage2 --interactive ASAN:SIGSEGV ================================================================= ==7051==ERROR: AddressSanitizer: SEGV on unknown address 0x00000000 (pc 0x00000000 sp 0xbeffe5f0 bp 0x37dffd15 T0) AddressSanitizer can not provide additional info. SUMMARY: AddressSanitizer: SEGV ??:0 ?? }}} `ghc-stage2` compiled with AddressSanitizer on `x86_64/linux` does not do the above. Unfortunately, while AddressSanitizer has found a problem, it doesn't provide any new information. I suspect it doesn't know enough about GHC's run time and calling conventions. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10375#comment:25 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
