A few thoughts: 1) Shouldn't global_lock be __LONG32?2) Would it make sense for the exchange on global_lock to be done as a single operation (ie InterlockedCompareExchange)?

I came up with a patch that fixes the issue for me. The patch replaces the global critical section with a spinlock. Critical sections require explicit initialization before use, which in this case is not possible: register_frame_ctor (from libgcc), which runs BEFORE enter_global_cs, tries to lock a mutex, which requires a spinlock, which needs to be initialized in static_spin_init, which tries to enter the global critical section, which is not initialized. The result is a segfault somewhere in ntdll. register_frame_ctor has constructor priority of 0, so setting the priority of global_spin_ctor wouldn't cut it. I'm not sure what is the official way to send patches, so I'm posting it here. ------------------------------------------------------------------------------ Sponsored by Intel(R) XDK Develop, test and display web and hybrid apps with a single code base.
