Sorry about that, I don't know why.
Does pthread_exit(0) use a __forced_unwind exception on
alpha-linux-gnu? This should tell you ...
#include <bits/cxxabi_forced.h>
#include <pthread.h>
void* f(void*) {
try
{
pthread_exit(0);
}
catch (__cxxabiv1::__forced_unwind const&)
{
__builtin_puts("unwind");
throw;
}
catch (...)
{
__builtin_puts("something else");
throw;
}
}
int main()
{
pthread_t t;
pthread_create(&t, 0, f, 0);
pthread_join(t, 0);
}

futex(0x12001a05c, FUTEX_WAIT_PRIVATE, 1, NULL
... the test hangs here ...
Could I get a stack trace of the remaining thread at that point?
