--- Comment #11 from Toon Moene <toon at moene dot org> --- Created attachment 49564 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=49564&action=edit The full program I am testing. This is the full program I am testing. I have compiled it as follows (after building the latest coarray_native branch): ~/compilers/install/coarray_native/bin/gfortran -g -fbacktrace -fcoarray=shared random-weather.f90 -lcaf_shared -lrt -lpthread and run it as: (export LD_LIBRARY_PATH=/home/toon/compilers/install/coarray_native/lib/gcc/x86_64-pc-linux-gnu/11.0.0; export GFORTRAN_NUM_IMAGES=N; echo ' &config / ' | ./a.out) It works with export GFORTRAN_NUM_IMAGES=2 ... 10 but crashes with a segmentation fault using export GFORTRAN_NUM_IMAGES=1 (besides, it gives bogus numbers when it runs - this is readily apparent by running the program compiled with -fcoarray=lib -lcaf_openmpi and compare). Hope this helps - I am looking forward to this alternative implementation of coarrays !
