In order to set up automated builds and tests of the CMake toolchain
(www.cmake.org) on HP-UX 11.11 (hppa) and 11.23 (ia64), I needed to install git
on those platforms.
The latest binary package available from hpux.connect.org.uk is version
184.108.40.206, which I installed with all of its dependencies.
When trying to set up the CMake build, I ran into the first problem:
$ git pull origin
error: cannot create thread: Function is not available
fatal: fetch-pack: unable to fork off sideband demultiplexer
So I examined the git source package and found that the author of the HP-UX
port forgot to set
in config.mak.autogen to enable threading. I added this setting and rebuilt
git. On 11.23, everything was fine now - no further issues.
On 11.11 though, git now crashed with a Bus Error. Some debugging showed that
this was due to a multithreading issue - obviously some dependency library has
not been built as reentrant code. To fix this, I disabled threading by setting
in config.mak.autogen and rebuilt git again. After that, "git pull" and "git
fetch" worked correctly and I could proceed to set up the CMake build and test.
Alas, the CMake tests include a test case "CTest.UpdateGIT" that creates a git
repository, creates a submodule, imports some content and attempts to check out
a revision. At that point, the command
git submodule init
fails with the output
Assertion failed: err == REG_ESPACE, file compat/regex/regexec.c, line 1096
No submodule mapping found in .gitmodules for path 'module'
and the stacktrace of the resulting core dump is

Since I'm no git expert (I'm not even a regular git user in fact), there's
nothing left for me to do except asking for help...
