Well, I've got a Core2 E8400. But at this point CPU differences
shouldn't matter at all: the JIT compiler isn't invoked and the
interpreter is CPU-model-agnostic.

And I've tested with both the released beta9 and git HEAD. Same
(positive) result here.

Try to recompile everything with debugging turned on and then set
a breakpoint at glCreateShader. You may have to wait for the
library to load and/or use the internal symbol name. Check the
argument it receives (in $rdi). Then set a breakpoint in the
calling frame and check the result it returns (in $rax).
