#11981: unknown symbol `__udivti3' when BuildFlavour = perf-llvm -------------------------------------+------------------------------------- Reporter: erikd | Owner: Type: bug | Status: new Priority: normal | Milestone: 8.0.2 Component: Compiler | Version: 8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Other | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by erikd): If I move `inplace/lib/bin/ghc-iserv` to `inplace/lib/bin/ghc-iserv.exe` and then created shell script at `inplace/lib/bin/ghc-iserv` containing: {{{ #!/bin/bash gdb --args inplace/lib/bin/ghc-iserv.exe $@ }}} Then I can run `ghc-iserv` under gdb and get a backtrace: {{{ Thread 1 "ghc-iserv.exe" received signal SIGSEGV, Segmentation fault. 0x0000000040aba3ff in ??
