 Stracing it reveals that it =

 Ah, sorry the full command was:
 strace =
git pull swedebugia

I looked at the strace output you p=
rovided, and didn't find any evidence
of a missing file, which I doubt w=
ould lead to the error message "unable
to fork" anyway=2E  The short exc=
erpt that you quoted in your earlier mail
showed the failure to find "/e=
tc/ld=2Eso=2Epreload", but that's expected,
and does not indicate a prob=
lem=2E  The problem might be happening in the
child process (/home/sdb/=
=2Eguix-profile/libexec/git-core/git), so adding
the -f option to strace=
, i=2Ee=2E "strace -f git pull swedebugia", might
yield more useful info=
rmation=2E

If I'm not mistaken, "unable to fork" more likely indicat=
es a lack of
available resources, possibly due to configured resource li=
mits (see
ulimit(3) and the 'ulimit' bash builtin, e=2Eg=2E try "ulimit =
-a")=2E
Otherwise, I guess it could be due to restrictions imposed by th=
e use of
a security framework=2E

Thanks for the -f tip=2E I thought the errors wer= e significant, but now I understood they are not=2E
I will reply to the thread with more information if upgrading does not sol= ve it=2E
It is a vanilla 0=2E16 with a few packages installed, no security framewor= k=2E

Git has been upgraded so I will try installing the newer version next=2E --
