| |
Hi , I have a program which will create multiple threads. One of the thread receives SIGSEGV and it prints stacktrace in its handler and calls _exit(-1). The call to exit wont terminate all threads in a process and hence thread hangs here. This causes resouce leaks and other problems. It is seen only on linux 2.4.20.
For printing stacktrace it uses __builtin_return_address and __builtin_frame_address
The same program works fine on linux 2.6.26 kernel. It will exit the whole process when one of its thread dies as above.
Please let me know the patch details or any workaround, if any. This is a bit urgent, so please let me know for any pointers , if any
Thanks and Best Regards, Pavan.
