See http://caml.inria.fr/mantis/view.php?id=4166 If we call only external functions from a module, then its 'let _' bindings don't get executed, which means that the exceptions don't get registered for use in the C code. This in turn causes llvm_raise to call raise_with_arg() with a NULL pointer and cause a segmentation fault. The workaround is to declare all 'external' functions as 'val' in these .mli files. Also added a separate testcase (the testcase must call only external functions for the bug to occur). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122497 91177308-0d34-0410-b5e6-96231b3b80d8
