I've recently updated my Gentoo Linux PC with GCC 5.4.0.
I also recompiled all packages depending on gcc (it was mentioned in gcc upgrade guide for gentoo).
Most of programs works well, however my tests, using cppunit, throw std::bad_alloc before starting.
At first I thought there might be a problem with updated version of cppunit, so I downgraded it to previous version, but the problem still exists.
Whenever I start any test, the application immediately throws:
terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
I started the application in gdb and printed debug backtrace:

There is no problem with test file itself, because I made no changes to it, and lots of test were working for long time.
After looking into stack trace, I'm pretty curious what happened on frame #12: __x=std::**__cxx1998**::vector of length **-2199020260704**, capacity **-2199020259433** = {...}
Why there is cxx1998? Both length and capacity looks pretty insane (uninitialized?).
TestSuiteBuilderContext.h:29:
void
TestSuiteBuilderContextBase::addTest( Test *test )
{
m_suite.addTest( test ); //line 29
}
TestSuite.cpp:
/// Adds a test to the suite.
void
TestSuite::addTest( Test *test )
{
m_tests.push_back( test );
}
I came up with partial solution.
It looks like the compile option:
-D_GLIBCXX_DEBUG
Was causing the problem. After removing it - tests run succesfully.
