[LLVMdev] JIT crash takes down host-application

Those shouldn't be crashes.

assert(foo) turns into:

if (! foo) {
    fprintf(stderr, ...assertmsg...);

abort() exits the program without the usual cleanup.  That's not a 
crash.  If you want an failed assertion to do something else, you can 
always define your own assert().

As for calling an external function that can't be resolved, perhaps 
there's a return code somewhere you're ignoring?
