Description Chris Lattner 2007-01-07 00:18:36 PST 
Consider this program:

#include <stdio.h>
static void exit(int X) {
  printf("myexit called\n");
}
int main() {
  exit(1);
}

This should print 'myexit called' once.  However:

$ llvm-gcc -c -emit-llvm t.c
$ lli t.o
myexit called
myexit called
ERROR: exit(-1073744072) returned!
Abort

This is due to the failures of the Module::getOrInsertFunction method.
