Package: mawk
Version: 1.3.3-17
Severity: normal
Hi,
I have found a bug in mawk. I wanted to strip HTML tags the dirty way, and
wanted to make a perlish non greedy match (i since discovered it wasn't
possible...), but on the way, i made a typo and executed this :
# You don't want to run this ;)
mawk '{gsub("<.+*>"," ")} NF > 0 {print}' /tmp/html
My computer was then half stuck, with _heavy_ memory allocation (malloc() bomb
like effect), mawk finally aborts when it has eaten all the RAM.
I know the RE is indeed stupid, i know it's an undefined behaviour, but my
system shouldn't be affected that way by a simple RE error :)
Please link '.+*' to '.+' (i don't know if it's sane...) or at least prevent
the
memory allocation hell !
Cheers,
François.
