Hi
It seems like git-diff-tree has some problems with moved files:
$ git-diff-tree -p --stat --summary -M
348f179e3195448cea49c98a79cce8c7f446ce26
343ca16424ba031b37e4df49afddaee098a8f347 | wc -l
*** glibc detected *** free(): invalid pointer: 0x12ecbbf0 ***
6101
As can be seen below there is some obvious error in the output just
prior to the crash:
drivers/w1/{masters => }/ds_w1_bridge.c | 38
This file is moved into "w1/masters" by commit

As shown above I can easily recreate the crash if you want more info.
Thank you for a wonderful tool.
