This is somewhat off-topic, but to my knowledge you want to catch *signals*, and not (only) exceptions. Signals are raised when you access invalid memory, dereference null-pointers, divide by 0 (on some architectures/compiler flags this raises a signal, as well as other floating point conditions) etc., so you want to install a signal handler:

  http://www.gnu.org/s/libc/manual/html_node/Signal-Handling.html

Especially these would be of interest:

  http://www.gnu.org/s/libc/manual/html_node/Program-Error-Signals.html#Program-Error-Signals

Refer e.g. to the implementation off http://www.codeproject.com/KB/debug/XCrashReportPt4.aspx (Win32)
