Hi all,

I can reproduce the issue in my machine (RedHat Enterprise 5, x86 PAE) as follows. 
But in my different machine (Fedora 16 x86) I can't reproduce.

  $ git reset --hard v1.8.1       # back to v1.8.1
  $ make clean 
  $ make all install               # this git works fine

  $ git pull                          # top commit 9a6c84e6, "Merge git://ozlabs.org/~paulus/gitk"
  $ make all install

  $ git fetch                         # this git segfaults
  Segmentation fault


So if there is any patch to test, just let me know  (but will not available during weekend).


Regards,
Jongman Heo

Great, thanks for taking the time to reproduce.

That makes me wonder if it is related to the gcc or make version. I
couldn't reproduce the problem on my gcc-4.1 system, though. My make is:

  $ make --version
  GNU Make 3.81
  [...]

After this step, what does builtin/.depend/fetch.o.d contain? It should
show a dependency of builtin/fetch.o on string-list (among other
things).

Can you try running "make -d builtin/fetch.o" here instead of "make all
install"? Can you confirm that it reads builtin/.depend/fetch.o, and
that fetch.o gets rebuilt (you should even be able to see the list of
"newer than" dependencies in the debug output)?

Another thing to double-check: does it work if you instead run

  make all install COMPUTE_HEADER_DEPENDENCIES=no

?
