Subject: setting categories with SMPI must always be after MPI_Init
X-Git-Tag: v3_5~350
X-Git-Url: http://info.iut-bm.univ-fcomte.fr/pub/gitweb/simgrid.git/commitdiff_plain/c3d226f96d4fa3cfef20972eac13b71d260decdd?ds=sidebyside

setting categories with SMPI must always be after MPI_Init

details:
- TRACE_smpi_set_category calls smpi_bench_end, which expects
that the smpi_bench was initialized
- programs will segfault if TRACE_smpi_set_category is called before
MPI_Init
