Hi all,
I know that when a thread in an application do invalid memory reference, OS generates SIGSEGV(segmentation fault) signal and terminates application. What if we handle this signal by defining a signal handler to perform to terminate only the thread did invalid memory reference. So, that the application will not be terminated. Also, is there any way, we can find when SIGSEGV is generated to get the invalid memory reference and thread id, who caused this fault. I know debuggers are written in such fashion. Can anyone point me to right direction. Thanks in advance. Perhaps phrack article in issue 58 file 03 could help you :) In case you're lazy, here's the URL:
http://www.phrack.org/issues.html?issue=58&id=3#article look for the section: "Subject: Getting rid of SIGSEGV - for fun but not for profit." A bit hackish, but I think it is worth to read.
