I created a self contained repro script that doesn't require you to have Java installed or any temp directories.
To run, just checkout branch pypy_bug in Krakatau (0d739be3707d3b3210fc1b2894a9e7b47334d215) and run pypy Krakatau/decompile.py -nauto -out temp -r -path Krakatau/tests/classes/ Krakatau/tests/classes/ 2016-02-14 14:51 GMT-08:00 Robert Grosse <n210241048...@gmail.com>: > 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.
