The backtrace is usually better for QEMU with TCG interpreter. Run configure --enable-tcg-interpreter The resulting binaries are much slower, but no longer create code on the fly, so you get normal backtraces. I also had to remove -fstack-protector-all (in file configure) to get good backtraces for w32/w64. Regards, Stefan
