--- Comment #1 from Pilar Latiesa <pilarlatiesa at gmail dot com> ---
It seems that combining -fopenmp and -fmodules is broken in GCC 15. It works
for me with GCC 14.
$ echo "export module m;" >> m.cpp
$ ~/gcc-15/bin/g++ -fmodules-ts -fopenmp -c m.cpp
/tmp/ccGdXgQl.s: Mensajes del ensamblador:
/tmp/ccGdXgQl.s:22: Error: el símbolo «_ZGIW1m» ya está definido
$ g++-14 -fmodules-ts -fopenmp -c m.cpp
$ g++-14 -v
Using built-in specs.
