@iwanowww I pinned down the problem with the MacOS x86_64 tests. It happens in the StringIndexOf test because we have UseAVX == 2 && EnableX86CoreOpts=true. The latter flag controls generation of the string_indexof_linear_ll/ul/uu stubs. I can reproduce the same error on my x86 corei7 box if I set EnableX86CoreOpts=true. The stubs add over 10000 bytes to the compiler stub blob -- without them there is only 8000 to spare. I have tweaked up the compiler blob sizing slightly (under LP64_ONLY) to allow room for them.
