Thanks! I uploaded it to the URL above.
The arm bits indeed trip TCG up:
/data/src/qemu (atomic-6 *$)$ for prog in \
$(find img/arm/ck_pr-armv7l/regressions/ck_pr/validate/ \
-executable -name 'ck_pr*' -type f); \
do \
arm-linux-user/qemu-arm $prog || break; \
done
qemu-arm: /data/src/qemu/tcg/tcg.c:653: tcg_temp_free_internal: Assertion
`ts->temp_allocated != 0' failed.
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Segmentation fault (core dumped)
/data/src/qemu (atomic-6 *$)$
Thanks,
