Re: php4 & phpmyadmin problem
Hi Almut,
first of all, thanks for your reply. I did what you said, now I sit here
with loads of output. After checking it, I guess the interesting stuff
is there (at the end of the log):
---------SNIP---------------

3819 read(8, "", 8192) = 0
3819 close(8) = 0
3819 --- SIGSEGV (Segmentation fault) @ 0 (0) ---

3819 kill(3819, SIGSEGV) = 0
3819 sigreturn() = ? (mask now [RTMIN])
3819 --- SIGSEGV (Segmentation fault) @ 0 (0) ---
-----------------
Before this, it opens other files in /usr/share/phpmyadmin/libraries,
but works ok. Maybe someone could help here? ;)
