Bug ID: 115491
Summary: Internal compiler error: in
resolve_typebound_procedure, at
fortran/resolve.cc:14913
Product: gcc
Version: 14.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: heinzell at ucar dot edu
Target Milestone: ---
I am working on a fairly complicated modeling code used by the U.S. Naval
Research Lab and I am hitting internal compiler errors that prevent us from
using gcc. I tested versions 10 through 14 (14.1.0), all with the same results.
It's going to be complicated to resolve, since I cannot share the code, but
hopefully we can find a way to address the problem.
This is the failing compile command in full glory. I added the flags you
recommended in your buz filing instructions. I can remove essentially all the
compiler flags, set the optimization to -O0 or any other value, remove all but
one include flag and remove all the preprocessor flags (see below) and I get
the same error:
$ /home/dom/prod/gcc-14.1.0-manual/bin/gfortran -c -fopenmp
-fmax-stack-var-size=65536 -fno-strict-aliasing -fwrapv

Since I cannot share the code and wasn't able to come up with a simple
reproducer yet (it's fairly complicated code using a lot of Fortran 2008 stuff,
including Fortran submodules), I am hoping to get some pointers on what I
should try. For instance, I don't even know which line in the source file it is
tripping over.
I appreciate your help very much! Thanks.
