Re: git diff looping?

I believe the issue is that Solaris implements 'extended' regular
expressions only in regcomp/regexec.  The implementation of
regcmp/regex seems to be from SysV and supports only 'basic' regular
expressions.

I can reproduce the problem on Solaris 8 using git v1.6.3. It seems to
be caused by a horribly slow system regex implementation; it really
chokes on the regex we use to find the "funcname" line for java files.

Hmm.  Is running under LC_ALL=C LANG=C _with_ the slow system regex help?

No, it remains extremely slow (it is possible that it _is_ faster,
though, but I never managed to run either case to completion; they are
both clearly orders of magnitude off of acceptable).

I haven't tried setting LC_ALL, LANG, but this Solaris regex is MANY orders
of magnitude slower.  I've been running your example diff on the egit
repository for 2 hours and it still hasn't finished.  The compat/regex
version finished in 3 seconds.  Solaris 10 x86.
