Michael Garriss said the following on 12/16/04 10:46:
from libs/thread/mutex.cpp in boost 1.31, around line 211:
void mutex::do_lock()
{
int res = 0;
res = pthread_mutex_lock(&m_mutex);
if (res == EDEADLK) throw lock_error();
assert(res == 0);
}
that last assert is failing for me. pthread_mutex_lock is returning 22
which if it's from sys/errno.h is EINVAL or "Invalid argument". any ideas?
i built boost 1.31 on hpux 11.11 with a gcc from hp. some info:
gcc -v

ok, this breaks with an assertrion failure:
#include
#include
#include <iostream>
struct count {
boost::mutex mutex;
count (int) { }
void operator()() {
boost::mutex::scoped_lock lock(mutex);
std::cout << "Here" << std::endl;
}
};
int main(void) {
count c(1);
boost::thread thrd1(boost::ref(c));
thrd1.join();
return 0;
}
but this does not:
#include
#include
boost::mutex mutex;
struct count {
count (int) { }
void operator()() { boost::mutex::scoped_lock lock(mutex); }
};
int main(void) {
boost::thread thrd1(count(0));
thrd1.join();
return 0;
}

it also breaks on making mutex a static class member. so in summary it
only works (i think) if the mutex is a member var.
