Bug 21488 – Bundled 32-bit dlang tools (ddemangle, dustmite, rdmd) segfault on startup

With official DMD v2.094.2 on Ubuntu 20.04: $ ~/dlang/dmd-2.094.2/linux/bin32/dustmite --version Segmentation fault (core dumped) $ ~/dlang/dmd-2.094.2/linux/bin32/rdmd --version Segmentation fault (core dumped) $ ~/dlang/dmd-2.094.2/linux/bin32/ddemangle Segmentation fault (core dumped) 32-bit dmd and dub executables work (presumably built by LDC), as do obviously all 64-bit ones.

Seems like it's just a bootstrap issue with the druntime/phobos library. --- $ cat reduce.d extern(C) int main() { static int* x = null; if (x is null) return 1; else return 0; } $ ./dmd2/linux/bin64/dmd -m32 -betterC reduce.d $ ./reduce Segmentation fault (core dumped) $ ./dmd2/linux/bin64/dmd -m32 -betterC reduce.d -fPIC $ ./reduce $ --- If all object files were compiled with -fPIC, then it's fine.
