             Bug #: 56388
           Summary: catch(...) in lambda rejected
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: omawarisan.bokudesu@live.jp


"g++ -std=c++11" rejects the following program:

int main()
{
    bool /*const*/ condition = false;

    [&]{
        try{}
        catch(...){
            if(condition){}
        }
    }();
}

If the condition variable is const, the compilation successes.

Using built-in specs.

The problem also exists for 4.7.2, so no regression. The diagnostics is
interesting:

"7:9: error: '...' handler must be the last handler for its try block
[-fpermissive]
catch(...){
^"

It's a regression from 4.6.
