It's hard to know if it's the compiler's fault without a test case - due to the nature of undefined behavior and other things (implementation defined behavior and unspecified behavior) in C++, that the program behaves as expected with another compiler or another set of flags doesn't give a strong indication as to where the problem is (in the code, in one of the compilers, etc).
