Package: gmsh
Version: 2.8.3+dfsg-4
Severity: important
Dear Maintainer,
debian/rules in gmsh package passes -fopenmp to CMake in debian/rules.
This results in experimental OPENMP feature silently enabled
( there is #if defined(_OPENMP) check in source) and then gmsh fails
sometimes with segfault as result of race condition.
I tried removing -fopenmp, package builds and gmsh seems to work.
from debian/rules:
ifeq (,$(filter $(DEB_HOST_ARCH),$(disable_mpi_archs)))
extra_flags += \
-DCMAKE_CXX_FLAGS="-DMPICH_SKIP_MPICXX -DOMPI_SKIP_MPICXX
-fopenmp -lmpi -fPIC \
-Wall $(shell dpkg-buildflags --get CXXFLAGS)" \
-DENABLE_MPI:BOOL=ON
else
extra_flags += \
-DCMAKE_CXX_FLAGS="-DMPICH_SKIP_MPICXX -DOMPI_SKIP_MPICXX
-fopenmp -fPIC \
-Wall $(shell dpkg-buildflags --get CXXFLAGS)" \
-DENABLE_MPI:BOOL=OFF
endif
Best Regards,
Petr Ledvina
