[LLVMdev] MCJIT crash on 64 bit Linux, works find on OSX

[Andy Somogyi]

Hi All.

I have an issue when a MCJIT ExecutionEngine is created then deleted, any C++ exception thrown after the MCJIT dtor is called will result in a seg fault. This does not occur with the regular JIT engine, and only occurs on Linux, works fine on OSX. 

basically its like this:

ExecutionEngine *e = engineBuilder.create();

// this is fine
try { throw exception()} catch(exception&) {}

delete e

e = engineBuilder.create();

// this will cause a segfault on 64 bit Linux, LLVM 3.4
// works fine on OSX
try { throw exception()} catch(exception&) {}

Any ideas?
