array = fgetcsv(fh, length[, delim]);

Documentation says length must be longer than the longest line including eol
chars. But it shouldn't gp fault.

Nice function. But it would sure be nice to not have to know the length of the 
longest line. This was a 75 mb file and it was 50% in that one line was 8K.

Easily reproduced. As soon as a line longer than the length parameter is 
encountered, immediate gp fault.

PHP caused an invalid page fault in
module KERNEL32.DLL at 016f:bff78769.

freebsd - php 4.0.2 core dumps on this also. php exits with message:
