Hello there ...
I am a researcher in the field of Distriputed computations and I am using
pthreads in constructing my concept.
I have to use the pthread_mutex_lock() and pthread_mutex_unlock functions
in order to define and use critical areeas in my code.
The problem I have is that when I use the purify tool for debugging memory
usage I find the following message with every run:
BSW: Beyond stack write error
This is occurring while in:
pthread_mutex_unlock [libthread.so.1]
_alloc_stack [libthread.so.1]
_alloc_thread [libthread.so.1]
_sys_thread_create [libthread.so.1]
_t0init [libthread.so.1]
_init [libthread.so.1]
Writing 1 byte to 0xefffc4f4.
Stack pointer 0xefffc4f8
If anyone has facesd a problem like this before ... please tell me what to
do ....
Thank you for your support.
