------- Comment #2 from zsojka at seznam dot cz 2010-01-26 19:30 -------
Created an attachment (id=19718)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=19718&action=view)
different reduced testcase
Reduced from gcc/builtins.c as well
This testcase started failing between r154830 and r154886 as well, so I am not
creating separate bugport for it.
All tested revisions fail at -O1, -O2 and -O3.
Command line:
gcc -O1 -fcompare-debug -c pr42878-2.c
or
gcc -O2 -fcompare-debug -c pr42878-2.c
or
gcc -O3 -fcompare-debug -c pr42878-2.c
