The following valid testcase triggers an ICE on trunk when compiled with "-O":
===========================
struct A
{
~A();
void foo();
};
void bar()
{
A a;
try
{
A b;
try
{
b.foo();
}
catch (int) {}
}
catch (int) {}
}
===========================
bug.cc: In function 'void bar()':
bug.cc:7: error: EH edge 2->21 is missing
bug.cc:7: error: unnecessary EH edge 2->10
bug.cc:7: internal compiler error: verify_flow_info failed
Please submit a full bug report, [etc.]
