--- Comment #9 from Fangrui Song <[email protected]> ---
A minimal reproduce:
% touch a.f90
% mpifort -fuse-ld=lld a.f90
ld.lld: error: corrupt input file: version definition index 0 for symbol
mpi_fortran_argv_null_ is out of bounds
>>> defined in /usr/lib/x86_64-linux-gnu/openmpi/lib/libmpi_usempif08.so
...
I believe lld's rigorous behavior regarding VER_NDX_LOCAL is correct.
Both openmpi and GNU ld have bugs. See
https://sourceware.org/bugzilla/show_bug.cgi?id=25236 (common symbol: don't
consider definitions in shared objects) and
https://github.com/open-mpi/ompi/issues/7209 (mpi_fortran_argv_null_ has
incorrect st_size in ompi/mpi/fortran/base/gen-mpi-mangling.pl)
Fixing either bug can make the lld linking problem go away.
