Detailed Description

Generate stack trace backs from a caught exception.

Date:
Oct, 2009 When an exception is caught, we'd sometimes want to dump out the stack at the point where the exception was thrown.

If you run with libexctrace_collector.so added to your LD_PRELOAD, then we'll remember the backtrace from the last exception thrown. You can then call CxxUtils::exctrace to print it out. This will behave sensibly if the collector module hasn't been preloaded (just print the exception, with no backtrace).
