[PATCH] Fix PR gdb/19208 - SIGSEV while opening Fortran program compiled with ifort


Hi all,

Find attached a patch that fixes a SIGSEV for me when trying to open a
Fortran program compiled with ifort (using version 16.0.1.150).
The error can be reproduced with a most simple file only containing "end"
and no additional compiler flags.
