The segmentation fault, was it when trying to run "pwd"? In that case,
I have never seen it before, but I _have_ seen it on setuid programs
(and netscape). The code that getcwd.so consists of is very
straight-forward, and I doubt that there are any bugs in it.
There have been speculations that the problem lies in the dynamic
linker, but this has not been confirmed.
If it occurs when running all programs, it's very bad, since the
getcwd.so is very vital for system functionality (as you have seen,
cwd fetching does not work very well without it). If you could do some
more testing, like when it segfaults and not, it would be very
valuable.
