you are right richard. it turns out i am generating too many tcg opcode in
the frontend, such that OPC_BUF_SIZE is too small.
Thank you

I am running QEMU user mode, but i hit a SIGSEV. It seems that tcg_malloc
returns invalid address.
The stack trace looks like this. and the s->nb_temps looks ok as well. I
also turned on DEBUG_TCGV and all the TCGV_X uses are good.
