A thread defined via a legacy MDEF that belongs to the FPU or SSE task group must set the thread option bits for FP or SSE register use prior to being spawned. If this is not done, and the kernel is configured for SSE support, the kernel will auto-enable the thread's use of floating point so that the thread saves SSE register context info even if it belongs to just the FPU task group, which could cause the thread to overflow its stack. Note that this change only increases footprint for x86-based applications that enable floating point register sharing.
