[4.0/4.1 regression]

[Joost VandeVondele]

Hi,

I've filed PR25218:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25218

which leads at -O3 to:

4.0.1
bug.c:20: internal compiler error: in compensate_edge, at reg-stack.c:2795
4.1
bug.c:20: internal compiler error: in initialize_original_copy_tables, at 
cfg.c:1025

Cheers,

Joost
