Bug 16031 – [REG2.071] stale DW.ref.name EH symbol used with -lib and -fPIC

make -f posix.mak MODEL=32 DMD=../dmd/src/dmd PIC=1 DMD v2.070-devel-1aa8a1e DEBUG Internal error: backend/elfobj.c 1040 posix.mak:184: recipe for target 'generated/linux/release/32/libdruntime.a' failed make: *** [generated/linux/release/32/libdruntime.a] Error 1 dmd from git, v2.071.1 (master HEAD too) linux x86 I'm not sure if this is a dmd regression, but the compilation worked in v2.0.70

(In reply to Martin Krejcirik from comment #0) > make -f posix.mak MODEL=32 DMD=../dmd/src/dmd PIC=1 What does the PIC=1 do? PIC isn't anywhere in posix.mak

(In reply to Walter Bright from comment #1) > What does the PIC=1 do? PIC isn't anywhere in posix.mak It's there, it adds -fPIC to DFLAGS.

Easy enough to guess that this is an issue with PIC and the new DWARF EH code. Seems like it was introduced by https://github.com/dlang/dmd/commit/58910e74854b7f7b86e5cec50a6d73943fc29f87, b/c Sdw_ref_idx gets cached but not reset before generating further objects. https://github.com/dlang/dmd/pull/6129
