[pypy-dev] Segfaults when compiling PyPy

Fri Mar 17 01:48:49 EDT 2017

Dear all,

Is there anyone also having the problem that CPython2.7 or PyPy2
randomly crashes when compiling PyPy (several latest versions on hg)?
I'm using Python 2.7.13 (or PyPy2 latest) on Debian stretch.

One kind of problems is https://bugs.python.org/issue29242

Another kind is shown below. (at 90736:e668451adc8d)

Program received signal SIGSEGV, Segmentation fault.
