Hi :),
I have a prog. with pthread semaphores. Everything works fine, but i
have a small problem with valgring.
If I commpile my program with
gcc -gdwarf-2 -O0 -static main.c -lpthread
and run as
valgrind --tool=helgrind --read-var-info=yes ./a.out
I get
==15757== Process terminating with default action of signal 11 (SIGSEGV)
==15757== Access not within mapped region at address 0xFFFFFFFFFFFFFFF8
==15757== at 0x4010B8: main (main.c:39)
==15757== If you believe this happened as a result of a stack
==15757== overflow in your program's main thread (unlikely but
==15757== possible), you can try to increase the size of the
==15757== main thread stack using the --main-stacksize= flag.
==15757== The main thread stack size used in this run was 8388608.
(on line 39 there is sem_post(sem), where sem is valid pointer on the
semaphore which is created by sem_open("test", O_CREAT, S_IRWXU, 1))
Is this normal? I am really confused...
Thanks,
John
(and sorry fo my english :D)
