Seems this is Fortran FE's fault, but I think we should both fix up Fortran FE and make expand_debug_expr more robust.
Created attachment 19952 [details] gcc45-pr43166.patch Patch that both robustifies cfgexpand and hopefully fixes Fortran FE common block handling.
Subject: Bug 43166 Author: jakub Date: Thu Feb 25 10:50:24 2010 New Revision: 157063 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=157063 Log: PR debug/43166 * cfgexpand.c (expand_debug_expr) <case VAR_DECL>: If mode is BLKmode, assert op0 is a MEM and just adjust its mode. * trans-common.c (build_common_decl): Also update DECL_MODE, and DECL_SIZE when encountering a larger common block and call layout_decl. * gfortran.dg/debug/pr43166.f: New test. Added: trunk/gcc/testsuite/gfortran.dg/debug/pr43166.f Modified: trunk/gcc/ChangeLog trunk/gcc/cfgexpand.c trunk/gcc/fortran/ChangeLog trunk/gcc/fortran/trans-common.c trunk/gcc/testsuite/ChangeLog
Fixed.
