Bug ID: 62272
Summary: Gimplify throws error on method call from inside
nested lambdas
Product: gcc
Version: 4.9.1
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: aaron.plavnick at spottradingllc dot com
Here is a minimal code sample, the bug exists in 4.7.3, 4.8.2, and 4.9.1. I
compiled with -std=c++11
--------------------------------------------
template< typename T >
class B
{
public:
void Foo() {}
void Bar()
{
[&]()
{
[&]() { Foo(); }();
}();
}
};
int main( int argc, char** argv )
{
B<int> b;
b.Bar();
return 0;
}
----------------------
The compiler returns:
main.cpp: In lambda function:
main.cpp:11:34: internal compiler error: in gimplify_var_or_parm_decl, at
gimplify.c:1741
[&]() { Foo(); }();
