Any further details? It doesn't seem like the pthread layout changed from 8.x to 9.1. Is it easy to reproduce w/ the test case of comment 5? --

SIGCANCEL is the signal used by pthread_suspend_np internally. The signal handler already deal with being in critical regions, hence it doesn't suffer from the deadlock. As it isn't allowed to overrride SIGCANCEL we imitated the behavior by poking in pthread guts (THR_IN_CRITICAL). --

Fairly simple to reproduce the problem.
cat > bug.d << CODE
import core.thread, core.sys.posix.pthread, core.stdc.stdio;
void loop()
{
pthread_attr_t attr;
pthread_attr_init(&attr);
auto thr = pthread_self();
while (true)
pthread_attr_get_np(thr, &attr);
}
void main()
{
auto thr = new Thread(&loop).start();
while (true)
{
thread_suspendAll();
thread_resumeAll();
printf(".");
}
}
