Hi,
I'm getting a segmentation fault on FreeBSD 5.4 using pthreads. I was
googling around and found that there are a lot of people hitting the
same bug, but didn't found a solution to it yet.
The active threads on my application are this ones:
(gdb) info threads
* 8 LWP 100052 0x2824231b in pthread_testcancel ()
from /usr/lib/libpthread.so.1
7 Thread 7 (sleeping) 0x2823a207 in pthread_mutexattr_init ()
from /usr/lib/libpthread.so.1
6 Thread 6 (LWP 100106) 0x282422fb in pthread_testcancel ()
from /usr/lib/libpthread.so.1
5 Thread 5 (sleeping) 0x2823a207 in pthread_mutexattr_init ()
from /usr/lib/libpthread.so.1
4 Thread 4 (sleeping) 0x2823a207 in pthread_mutexattr_init ()
from /usr/lib/libpthread.so.1
3 Thread 3 (runnable) 0x2836af7b in select () from /lib/libc.so.5
2 Thread 2 (sleeping) 0x2823a207 in pthread_mutexattr_init ()
from /usr/lib/libpthread.so.1
1 Thread 1 (runnable) 0x283d49ff in flockfile () from /lib/libc.so.5
My application runs ok on other platforms (Linux and Mac OS X) and
since there are a lot of people hitting the same bug ( always
pthread_testcancel() & pthread_mutexattr_init() around ) I think that
there must be something wrong in FreeBSD pthreads implementation.
I really need to find a solution to my problem as soon as possible.
Does anyone have a solution to this ?
I've talked to a guy that is hitting the same problem and he told me
that this is not fixed on FreeBSD 6.0.
Thanks a lot.
