Hi,
when trying to compile the attached program with mpiCC I get a
segmentation fault on executing. I compile it with
OMPI_CXX=g++48 mpicxx -g test.cpp
Output on running the compiled program:
~> ./a.out
zsh: segmentation fault (core dumped) ./a.out
I have no idea what's wrong with it. The code seems fine (to me) and
compiling c code or using clang works without problems. Any input on
that?
Attached is the code that crashes and the backtrace of the crash.
Regards,
Gideon Lang
