[Bug debug/25197] New: ICE: RTL check: expected code 'reg', have 'plus' in dwarf2out_frame_debug_expr, at dwarf2out.c:1781

[aj at gcc dot gnu dot org]

compare the following two testresults:
http://gcc.gnu.org/ml/gcc-testresults/2005-12/msg00008.html
http://gcc.gnu.org/ml/gcc-testresults/2005-11/msg01430.html

The newer one gets additional failures e.g.:
FAIL: gcc.c-torture/compile/20050622-1.c  -O3 -g  (test for excess errors)
FAIL: gcc.c-torture/execute/20040805-1.c compilation,  -O3 -g 

The failure is the same ICE for all new failures:

/aj-cvs/gcc-svn/trunk/gcc/testsuite/gcc.c-torture/execute/20040805-1.c  -w  -O3
