The problematic line expands to:
static pthread_mutex_t __global_lock(PTHREAD_MUTEX_INITIALIZER);
which is clearly wrong when PTHREAD_MUTEX_INITIALIZER is of the form {...}
As you suggest, it should be using gthreads, but a simpler fix for now would be
to avoid using _GLIBCXX_PROFILE_DEFINE_DATA and declare __get___global_lock
directly in profiler_trace.h, something like:
inline __mutex_t& __get___global_lock() {
static __mutex_t __global_lock = PTHREAD_MUTEX_INITIALIZER;
return __global_lock;
}
