I tested that again with vanilla 2.4.16 patched against suse-2.4.16-7.bz2
from Hubert Mantel (i did not want to download the ~13 MB rpm file - i
only have a slow ISDN dialup connection ;-( ).
The result is the same as with 2.4.15aa1. top and man both segfault.

I searched a little bit in the source codes and found out that both
programs seem to have bugs that causes them to operate with zero pointers.

Best regards,
