This seems to be well-known problem with interacting setjmp/longjmp and optimization passes. Actually, this is LLVM PR1520. The problem is that setjmp/longjmp changes codeflow in inpredictable manner (especially, if jump buffer escapes from function). We need some clever idea how to represent such stuff. PS: Compiling with -O0 should be easy workaround. -- With best regards, Anton Korobeynikov. Faculty of Mathematics & Mechanics, Saint Petersburg State University.
