I think I might have found a bug in the exection engine's 'constants folding'. Basically APInt's parameters are the wrong way round. Line 577 for lib/ExecutionEngine/ExecutionEngine.cpp :- case Instruction::PtrToInt: { GenericValue GV = getConstantValue(Op0); uint32_t PtrWidth = TD->getPointerSizeInBits(); GV.IntVal = APInt(PtrWidth, uintptr_t(GV.PointerVal)); return GV; } Aaron -------------- next part -------------- An HTML attachment was scrubbed...

Hi David, In pretty sure that the crash is due to the instruction I have shared in my first email. In order to run pngpixel you just need libpng and zlib.. honest I thought that the .bc had Al the necessary. I'm happy to help you to reproduce it. As a curiosity, why do you think you cannot reproduce it? Unfortunately I won't be able to modify the interpreter soon.. anyway, I'll try to

I have a frontend that generates some LLVM bitcode that needs to be linked with other bitcode (its runtime library), which I generate from C++ source using Clang. If I write the output of my program to disk, link it with llvm-link, and then run it with lli, everything works perfectly. But if I try to perform the linking and running steps in my main program, I get this error during
