Answer 1

It looks like gcc being killed due to insufficient memory (see @Blender's comment) exposed a bug in pip. It mixes bytestrings and Unicode while logging that leads to:

>>> '\n'.join(['bytestring with non-ascii character ☺', u'unicode'])
Traceback (most recent call last):
  File "", line 1, in 
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 36: \
   ordinal not in range(128)

If it is reproducible with the latest pip version; you could report the bug.
