             Bug #: 52619
           Summary: ICE/segmentation fault in lambda function
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: t.schu...@web.de


Hi, the following piece of code causes an ICE (segmentation fault) when
compiled with gcc-4.7.0-RC-20120302 (no problem with gcc 4.6.3):

#include <atomic>

template<typename T>
struct test {
  std::atomic<int> x;
  void foo() {
    auto cond = [this] {return x != 0;};
  }
};

It works if the value of x is loaded explicitly:

auto cond = [this] {return x.load() != 0;};
