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: unassigned@gcc.gnu.org
ReportedBy: 0ezpz0@gmail.com
Created attachment 27719
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27719
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.

Simplified testcase:
struct T { T () : t(0) {}; int t; ~T (); };
struct S { void *operator [] (T); };
void bar (S &, void *, void *);
void
foo (S &x, T &y)
{
bar (x, &&l1, &&l2);
l1:
goto *x[y];
l2:
bar (x, &&l1, &&l2);
}
