Product: gcc
Version: 4.6.0

Priority: P3
Component: debug
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: zsojka@seznam.cz
CC: aoliva@gcc.gnu.org
Host: x86_64-pc-linux-gnu
Target: x86_64-pc-linux-gnu

preprocessed source
Compiler output:
$ gcc -O -fprofile-generate -fcompare-debug testcase.C -w
gcc: error: testcase.C: -fcompare-debug failure (length)
The original source fails with r165699, but the reduced one doesn't... I don't
know if this is a regression or not.
