I've also had problems with threads on sparc64 (specifically, mozilla
locks up or crashes a lot).

Er, well, questions is not a bug-reporting channel, and it is not even
read by most developers.  Bug reports should be submitted via send-pr,
and/or reported to the relevant technical mailing lists.  sparc64 (and
threads) is definitely the place for this mail.  Please re-send it
there and/or submit a PR, since you have a working test-case that
exposes the problem.

Threads problem on 5.1-Release sparc64

[Steven Haywood]

Hi folks

I'm still having pthreads problems on Sparc64 (5.1 Release):
The program concerned is:
# cat conftest.c
#include 

void* routine(void* p){return NULL;}

int main(){
  pthread_t p;
  if(pthread_create(&p,NULL,routine,NULL)!=0)
return 1;
  (void)pthread_detach(p);
  return 0;
}


Compiled with:
 gcc -o moo -lc_r conftest.c
no errors

Trying to run it:
