I would in case the chdir failed try some more or less convenient places:

GV_LIBDIR    (the resource files aren't thought to be a problem)
/      (normally not writeable for ordinary users, so usually you won't
find problematic files there, should work)
Perhaps creating some empty directory in /tmp or $HOME?
Sounds good.
and is it really necessary to quit the whole program on chmod error?
Only the child is exited (that would replace itself with gs, or quit in
the same way when gs cannot be started...)
Well, I see.

But in src/psscan.c  (psscan), we have

      if (system(cmd) || file_fileIsNotUseful(filename_dsc)) {

which is used to call call ps2dsc. So it did not pass the chdir done on childs...

I'm sure that has not changed since 3.6.5 and even longer.
