Re: [pypy-dev] What is the last good build of Pypy?

14 Feb 2016


      I tried running pypy under gdb, and it turns out that while it crashes at a
nondeterminstic point in the Python program, the segfault always appears at
the same location in the pypy binary. Here's a backtrace

The following steps should let you reproduce it. It segfaults for me every
time. Though interestingly, the actual place it segfaults changes from run
to run.
First checkout Krakatau a43b2e7e0a53bca9fe7c34d97b3b3738d662f8d5 (the
latest)
Then run
pypy Krakatau/decompile.py -out <tempdir> -nauto -skip <path to rt.jar>
where <tempdir> is any writeable directory. For example
pypy Krakatau/decompile.py -out temp -nauto -skip
/usr/lib/jvm/java-8-oracle/jre/lib/rt.jar
Decompiling almost anything segfaults, but this is the simplest setup.
Feel free to respond if you still can't reproduce it.

The segfaults only started last week. I suspect that one of my recent
changes triggers the segfault behavior in Pypy. Can you try with the latest
version of Krakatau? If you still can't reproduce it, I can try to figure
out the steps in more detail.

ok, I used krakatau in the past and it worked, so you need to be more
specific. Notably give me an example program, how to run it etc. I
need to be able to confirm your steps step by step
...
Pypy segfaults every time I try to decompile an app with Krakatau. The
same
code still works on CPython (it's just a lot slower obviously). I'll
...
narrow down the circumstances and come up with better repro
instructions
later.
This happened on my build from November too, so it's not a recent
regression. And it happened on multiple computers, although I built
Pypy
from source in both cases, so there could be something going wrong

Hi Robert
You need to explain in details what are you doing and how can we

I updated Pypy, but I'm still getting random segfaults. Is there
any way
to
see what the problem might be? It just says segfault, so there's no
information. Also, the same code works in CPython.
