rax            0x10000010       268435472
rbx            0x7fff5fbff380   140734799803264
rcx            0x7fff5bc00380   140734732698496
rdx            0x10000000       268435456
rsi            0x7fff4fbfc380   140734531355520
rdi            0x0      0
rbp            0x7fff5fbff4a0   0x7fff5fbff4a0
rsp            0x7fff5fbff380   0x7fff5fbff380

.. so it looks like the requested stack frame size is circa 256Mb .. 
(c.f. Darwin's 64-sih Mb).
