Bug #: 53812
Summary: lower_stmt (4.6), verify_gimple_stmt (4.7.0, 4.7.1)
Classification: Unclassified
Product: gcc
Version: 4.7.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: 0ez...@gmail.com

preprocessed source
The attached code causes internal compiler error for 4.6.3, 4.7.0, and 4.7.1.
Same reported location as #53356 but happening in 4.7.1.
I was unable to reduce to a smaller example that would still expose the
problem.
Here is the full output of g++ -v -save-temps (for g++-4.7.1)
Using built-in specs.
