arch_setjmp.S stores d8-d15 only under CONFIG_ARCH_FPU, but it did not include nuttx/config.h. So setjmp() never saved these registers and longjmp() never restored them. They are callee-saved (AAPCS64), so a function that kept a value in one of them could see it change after a longjmp(). Include nuttx/config.h. The assembly then stores d8-d15, eight bytes each, at offsets 112 to 176. struct setjmp_buf_s declared them as eight 4-byte floats, 32 bytes short, so declare them as uint64_t too. jmp_buf is now 176 bytes with the FPU, and its layout matches the assembly.
