Package: pypy
Version: 7.2.0~rc0+dfsg-1
Severity: normal
User: debian-...@lists.debian.org
Usertags: armhf
Control: affects -1 pypy3

Observable since 7.2.0~rc0+dfsg-1 we've seen occasional SIGILLs and SEGV
with pypy's armhf build running on Armada XP boards (arnold, hoiby,
hartmann, henze).

https://buildd.debian.org/status/logs.php?pkg=pypy&arch=armhf
e.g. 
https://buildd.debian.org/status/fetch.php?pkg=pypy&arch=armhf&ver=7.2.0%7Erc0%2Bdfsg-1&stamp=1570119992&raw=0

Reproduces at least 50% of the time on abel, the Armada XP porterbox.
This was an attempt to build pypy3 7.3.4~rc1+dfsg-1 with pypy 7.3.3+dfsg-1.

Core was generated by `pypy --jit loop_longevity=300 -u 
/home/stefanor/pypy3-7.3.4~rc1+dfsg/rpython/bi'.
Program terminated with signal SIGILL, Illegal instruction.

Seems like this is probably an issue with flushing the I-cache after generating
jit-code, but as far as I can see, pypy is doing the right thing, calling
__clear_cache after writing jit-code:
