This looks like it is
memory corruption (e.g. someone overwriting a free'd segment),
but that sort of memory corruption is very hard to track down.

OK, so the version you have (58ba4) is the latest fast-import after
the strbuf.c series went in.  The one immediately before that series
was 4bf538 and is probably actually stable.

So I wonder, can you test 4bf538 and then if it is good bisect
between those two commits?  There must be a memory corruption
introduced by one of the strbuf changes...

  Gasp, if you get the offending sha1 commit, don't forget to Cc: me.

  Okay, given that fast-import uses quote_c_style, I believe this is the
same but that the one that was reported already. I've read the full
`git diff 4bf53833dbca666f61b5177977e96d453527db20.. -- fast-import.c`
and nothing alarming shows up.

  Please try to apply:
http://git.madism.org/?p=git.git;a=commit;h=7406e83342cd445ac38c1753c5fce75377737e2f

  And see if that fixes the issue for you. Else a bisection would be
much appreciated. Thanks.
