test t1050.large fails

[Ali Tofigh <alix.tofigh@xxxxxxxxx>]

I'm trying to compile git from source on a linux machine and "make
test" fails unexpectedly. Specifically test t1050.large.sh fails
(details below). The test fails both in version 1.7.11.4 and on the
master branch. Can I trust and use the build? if not, could someone
help me figure out what is going on?

Below are the contents of the test output (t1050-large.out):
