[LLVMdev] LLVM 3.2: conflict with Ubuntu 12.04's version 3.0 of LLVM

[Alan Garny]

Hi,

I am working on a Qt project which relies on various plugins, one of which being an LLVM plugin which I build from the LLVM 3.2 source code. Everything works fine on Windows and OS X, but not on Ubuntu 12.04.

Basically, my application runs fine, but when I close it I get a "Segmentation fault (core dumped)". Debugging my application, I found out that, upon shutting down, my application tries to call Ubuntu's version of LLVM (see below for the debug trace). To convince myself that it was really the case, I sudo renamed Ubuntu's LLVM library and rerun my application. As expected, everything worked fine (i.e. no segmentation fault).

Now, it's clearly not an issue with LLVM itself, but a google search didn't yield anything useful, so I was hoping that someone else might have come across this issue before and, more importantly, would have found a solution for it...

Cheers, Alan.
