[Beignet] building on Fedora 28, gbe_bin_generater fails

Fri May 4 09:44:47 UTC 2018

I'm trying to build the latest Beignet from git on Fedora 28 using gcc 
8.0, but the build fails when calling gbe_bin_generater with the 
following error:

/usr/include/c++/8/bits/stl_vector.h:932: std::vector<_Tp, 
_Alloc>::reference std::vector<_Tp, _Alloc>::operator[](std::vector<_Tp, 
_Alloc>::size_type) [with _Tp = clang::IdentifierInfo*; _Alloc = 
std::allocator<clang::IdentifierInfo*>; std::vector<_Tp, 
_Alloc>::reference = clang::IdentifierInfo*&; std::vector<_Tp, 
_Alloc>::size_type = long unsigned int]: Assertion '__builtin_expect(__n 
< this->size(), true)' failed.

Specifically gbe_bin_generater crashed when executing:

    733     std::unique_ptr<clang::CodeGenAction> Act(new 
clang::EmitLLVMOnlyAction(llvm_ctx));
    734
    735     auto retVal = Clang.ExecuteAction(*Act);

in beignet/backend/src/backend/program.cpp. As far as I can tell the 
source and the build options seem to be passed correctly.

Here's the complete backtrace:

I'd be grateful for any hint on what the problem might be.

Cheers,
