Re: grep 2.5: --only for long line runs forever

[Sven Hartrumpf]

The problem disappears when I run the same grep-2.5 binary on a more recent
Linux distribution (SuSE 8.1 instead of SuSE 7.2). So, an old libc or old 
libpcre 
is the culprit, not grep itself.
I think I will upgrade Linux or use a recent gawk.
Thanks for all your help
Sven

P.S.
Under SuSE 7.2 backtraces on endlessly running grep looks like this:
