            Bug ID: 59831
           Summary: ice in cgraph_speculative_call_info with -O3
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

Created attachment 31845
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=31845&action=edit
gzipped C++ source code

I just compiled the attached code with gcc trunk 20140115 on a x86_64
box with flag -O3 and it said

In file included from StringA.h:32:0,
                 from file.h:33,
                 from file.C:33:
VarArray.h: In function ‘T& VarArray<T>::operator[](int) [with T = string]’:

This looks different to bug # 58477 to me.
