Hmm it looks quite strange, looking quickly at the code, the only place
were we have a variable and unsafe length passed to tcg_gen_deposit_i64
is when using MIPS64R2 instruction, which is not your case according to
the previous mail as you said you pass -cpu 5Kc to qemu. I remember
there was a patch to fix these instrucions on the mailing list

The best would be to get a backtrace using gdb so that we can now what
calls tcg_gen_deposit_i64 with this too big len.
