no...

Weird, it definitely shouldn't be crashing. How did you create your module? -eric On Tue, Aug 12, 2014 at 12:56 AM, Tianyin Xu <tixu at cs.ucsd.edu> wrote:> no...

I just follow the tutorial: http://llvm.org/docs/WritingAnLLVMPass.html Actually it's not only my module, I used the LLVMHello.so (a sample module in the source tree) and get the crash (I didn't do anything :-P). ~t On Tue, Aug 12, 2014 at 12:57 AM, Eric Christopher <echristo at gmail.com> wrote:> Weird, it definitely shouldn't be crashing.
