Actually GHC does exactly that when you compile with -prof -auto-all. Then if you run with +RTS -xc, you get a backtrace of sorts. (I have not tested this recently!) The backtrace is not yet reified into a data structure that can be examined, but that'd be quite doable if someone wanted to try.
A major problem with this that I notice is that it dumps the stack whenever any exception is raised, which is a big pain if your program does IO and regularly raises and catches exceptions as part of normal operation. A big improvement would be to only dump the backtrace if the exception was uncaught and caused the program to abort. John -- John Meacham - ⑆repetae.net⑆john⑈
