Description
Windows x64 ABI requires caller to allocate space for parameters to the callee, and must always allocate sufficient space for the 4 register parameters, even if the callee doesn���t have that many parameters. Stubs for G1 pre- and post- barriers do not reserve the spill space so the stack gets corrupted.
