[llvm-dev] LLVM crash on iOS simulator

[Ramakrishna Mallireddy via llvm-dev]

libLLVMContainer.dylib is from opengles.framework, I am not using it
myself. iOS may be loaded it by default.

I have compiled llvm core & support libs along with my simple test code,
yet the llvmcontainer.dylib conflicts with my code.

How can I get around this conflict issue.

Thanks
Ramakrishna
