Bug #: 55138
Summary: [4.7 Regression] inlining fails with -O2 on gcc 4.7.2
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: tree-optimization
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: konstantin.vladimirov@gmail.com

reproduction
found on private target, but can be easily reproduced on x86, so I think every
target is affected.
Compile attached file on gcc-4.7.2 with -O2 -DBROKEN to make function inlined.
Next run. You will see error. Compile just with -O2, next run and you will see
no error.
This error can not be reproduced on gcc-4.6.3, everything works fine. Problems
starts with 4.7

reduced test case in C
C++ not needed, fails also in C, works with gcc-4.6.3

Looks like a dup of PR54985 to me.

Backporting the PR54985 fixes (r192745, r192746, r192754, and r192852) to 4.7
does fix this PR's reduced test case.
