------- Comment #4 from burnus at gcc dot gnu dot org 2007-02-06 16:34 ------- Not that it much helps, but with today's gcc under x86_64-unknown-linux-gnu it does not crash. Maybe someone with Intel Mac can reproduce it.
Oherwise: Compile with the "-v" option, e.g. gfortran -v -O3 env_grid.f After the line "gcc-Version 4.3.0 20070206 (experimental)" is the actual compilation command. On my computer it looks like: /projects/tob/gcc-trunk/libexec/gcc/x86_64-unknown-linux-gnu/4.3.0/f951 env_grid.f -ffixed-form ... Run now (replace the argument with yours of above) gdb /projects/tob/gcc-trunk/libexec/gcc/x86_64-unknown-linux-gnu/4.3.0/f951 (gdb) b real_abort (gdb) b fancy_abort (gdb) run env_grid.f -ffixed-form (... and the rest of the options) When it stops, enter (gdb) bt This gives a backtrace and a hint where the error occurs. What exact version of gfortran did you try? Do you know by chance whether this is a new problem or was present in a previous version of gfortran 4.3? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30713
