Infinite Loop when calling a mock function that takes boost::filesystem::path as parameter #170

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Minimal example:

---------------------
#include "gtest/gtest.h"
#include "gmock/gmock.h"
#include <boost/filesystem.hpp>

class MyMock {
public:
  MOCK_METHOD1(func, void(const boost::filesystem::path &path));
};

TEST(MyTest, mockTest) {
  MyMock mock;
  mock.func(boost::filesystem::path("/myfile"));
}
-------------------

When running this test (using gtest 1.7.0 and gmock 1.7.0 on linux 64bit with 
g++ (Ubuntu 4.9.1-16ubuntu6)), it aborts with a SIGSEV.
gdb shows that the SIGSEV is raised in malloc(), while the stack is very large 
and contains a short periodic set of functions calling each other in a circle. 
I assume there is an infinite loop.

The interesting part of the stacktrace is here:

btw I'm using libboost-filesystem in version 1.55

Can you make an even more minimal example that doesn't depend on Boost?
I'd like to know what it is about boost::filesystem::path that makes this 
happen.

I tried to, but gave up after some hours. It is quite complicated to resolve 
all the inner boost dependencies, boost::filesystem::path is having.
