I have also observed the following QEMU crash:

qemu-mipsel: qemu/accel/tcg/cpu-exec.c:634: cpu_loop_exec_tb: Assertion `use_icount' failed.
qemu: uncaught target signal 11 (Segmentation fault) - core dumped

It occurred when compiling Perl, and it seems to be identical to this bug
reported by John Paul Adrian Glaubitz for SH4:
