This assertion occured with latest git master: qemu-system-mipsel: /src/qemu/tcg/tcg-op.h:2589: tcg_gen_goto_tb: Assertion `(tcg_ctx.goto_tb_issue_mask & (1 << idx)) == 0' failed. Aborted
QEMU was built with --enable-debug and running a Debian MIPS Lenny (NFS root). The assertion happened when running "apt-get update" in the guest. Regards, Stefan W.
