Hi all,

I am trying to build a custom Conda installer for Python 3.6.0b4. I could successfully build an run Python. However, when I run the generated Conda installer, it dies with a "Bus error". It happens when Conda's meta-installer script tries to replace the build-prefix (e.g., /home/stefan/conda/asdf) with the prefix of the actual installation (e.g., /tmp/py36). Therefore, it opens all files in binary mode, reads their contents, replaces stuff, and writes the new contents back to the original file. This works fine with text files but it dies when it hits the first binary file. Here is a minimal example that reproduces the error: $ /tmp/py36/bin/python Python 3.6.0b4 (default, Nov 22 2016, 10:32:29) [GCC 6.2.1 20160916 (Red Hat 6.2.1-2)] on linux >>> >>> path = '/tmp/py36/lib/libpython3.6m.so.1.0' >>> f = open(path, 'wb') BusError

You'll have to investigate yourself. First enable core dumps ("ulimit -c unlimited"), then run gdb on the resulting core dump.

(or run Python directly under gdb)

Regards

Antoine.
