Thanks, all. I change to install an exception handler rather signal handler with api InstallExceptionHandler(), and in my exception handler, I firstly invoke some other tool to collect information, and then return -1, so the crash report dialog will be shown. But it still exist a problem: does the InstallExceptionHandler only affect the current thread? If I crash in other thread, will my exception handler be invoked?

It's not ideal because you can't really rethrow the abort with the same stack, you will always show as being in the trap handler (the stack for a crash report looks something like this (on a PPC): It's also not ideal because printf() is not signal-handler-safe. ;-) This email sent to zhanglin.zhou@gmail.com This email sent to site_archiver@lists.apple.com
