Markus Trippelsdorf <markus at trippelsdorf dot de> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |markus at trippelsdorf dot | |de --- Comment #1 from Markus Trippelsdorf <markus at trippelsdorf dot de> 2012-05-05 09:14:29 UTC --- Started with revision 186579. Reduced: int a; char b; void fn1 () { a = (unsigned char)b; switch (a) { case '\0': case -1: return; default: fn1 (); } } (dcb please have a look at http://gcc.gnu.org/wiki/A_guide_to_testcase_reduction. It's would be easier if you could reduce your testcases yourself and it isn't that hard, actually.)
