New issue 2239: Segfault in replace_guard_class_with_guard_value
https://bitbucket.org/pypy/pypy/issues/2239/segfault-in
uncaffeinated:
Pypy segfaults whenever you try to decompile anything with Krakatau.
To reproduce, checkout Krakatau branch pypy_bug
(0d739be3707d3b3210fc1b2894a9e7b47334d215) and run
pypy Krakatau/decompile.py -nauto -out temp -r -path Krakatau/tests/classes/
Krakatau/tests/classes/
gdb backtrace:
Program received signal SIGSEGV, Segmentation fault.
