The failing program.
I compiled the attached program as follows:
~/compilers/install/coarray_native/bin/gfortran -fbacktrace -fcoarray=shared
test-coarrays.f90 -lcaf_shared -lrt -lpthread
and ran it:
(export
LD_LIBRARY_PATH=/home/toon/compilers/install/coarray_native/lib/gcc/x86_64-pc-linux-gnu/11.0.0;
export GFORTRAN_NUM_IMAGES=1; echo ' &config / ' | ./a.out)
Decomposition information on image 1 : there are 1 * 1 slabs; the slab on
this image has 90 * 90 grid cells.
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
