Corrupted stack - Why Ubuntu 7.10 does not have libsafe; does not show errors in ?
Hi people, I am fighting with stack corruption problem in my appilcation I wanted to use libsafe , but debian/ubuntu packages are not accessible, so I built libsafe manually from source tar distribution And now, I see from trace ouput that altough my calls are indeed intercepted in preloaded libsafe functions, no errors are shown neither in stderr, nor in /var/log/secure Any advises are heartly welcomed Toda, L. = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

You can try to use valgrind.

Hi Valery, I do use valgrind to find memory leaks, but libsafe suppose to directly get me the name of function where stack is smashed. I forgot to write, that in order to disable GCC stack protectin, I compile my application and libsafe with -fno-stack-protector option. Valery Reznic wrote: You can try to use valgrind.

when you can use valgrind - most other things are pretty useless. did you encounter a memory-handling bug that valgrind failed to catch, while another tool (such as libsafe) did catch? note: i never used libsafe, so i might be missing something - i simply compared valgrind to many other available tools in the past, and nothing (except for commercial software such as purify) came close. --guy Lev Olshvang wrote: Hi Valery, I do use valgrind to find memory leaks, but libsafe suppose to directly get me the name of function where stack is smashed.
