[Bug fortran/69659] [6 Regression] ICE on using option -frepack-arrays, in gfc_conv_descriptor_data_get


https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69659

--- Comment #6 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
I have run

make -k -j8 check-gfortran
RUNTESTFLAGS="--target_board=unix'{-m32/-frepack-arrays,-m64/-frepack-arrays,-m32,-m64}'"

Before the patch, the number of FAILs is 1123, 234 of them being related to
ICES.
After the patch, the number of FAILs is 497, 18 of them being related to ICES.

These unfixed ICEs are related to compilations with -Warray-temporaries, e.g.,
gfortran.dg/dependency_3[56].f90
gfortran.dg/inline_(sum|transpose)_1.f90

and the errors are of kind

in gfc_format_decoder, at fortran/error.c:937

I'll try to fill a new PR for this problem.
