[Converted from Gnats 940] Customers asked that Intel compiler will able to support value DW_LANG_Fortran95 for attribute DW_AT_language. But this fix is impossible in present time because GDB reports about its 'internal errors' in this case. Release: unknown Environment: 32-bit && 64-bit Linux.
I see DW_LANG_Fortran95 in set_cu_language. So, I would guess that this should work just fine. Can you be more specific about what internal error you see? Or what version of gdb you are using?
I think this was fixed a while ago.
