#14894: HEAD fails to build with -g1 -------------------------------------+------------------------------------- Reporter: niteria | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.5 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: x86_64 Type of failure: Debugging | (amd64) information is incorrect | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by niteria): Actually, building GHC is overkill. This reproduces on many tests when `-g1` is used. For example: {{{ =====> simplCore.oneShot(optasm) 1 of 1 [0, 0, 0] cd "./prog003/simplCore.oneShot.run" && "/data/users/bnitka/ghc-HEAD- dwarf-lint-fixes-validate/inplace/test spaces/ghc-stage2" --make -o simplCore.oneShot OneShot2 -dcore-lint -dcmm-lint -no-user-package-db -rtsopts -fno-warn-missed-specialisations -fshow-warning-groups -fdiagnostics-color=never -fno-diagnostics-show-caret -g1 -dno-debug- output -O -fasm -v0 Compile failed (exit code 1) errors were: OneShot2.o(.debug_info+0x1bb): error: undefined reference to '.Lc5rU_die' OneShot2.o(.debug_info+0x1e3): error: undefined reference to '.Lc5rU_die' OneShot2.o(.debug_info+0x291): error: undefined reference to '.Lc5w8_die' OneShot2.o(.debug_info+0x2b9): error: undefined reference to '.Lc5wf_die' collect2: error: ld returned 1 exit status `gcc' failed in phase `Linker'.
