Where to report bugs found in slackware64-current?

Hello,
I found bug in slackware current update (procps-ng) and would like to report it.
How to do it?
I wrote an e-mail to webmaster@slackware.com and info@slackware.com that I get from slackware.com, but these emails doesn't exists.

I use slackware64-current on few hosts. After last upgrade I found that pgrep command doesn't work.

I tested it on few installations.

$ pgrep x
pgrep: cannot allocate 4611686018427387903 bytes

pgrep is used by /etc/rc.d/rc.* scripts and as example rc.networkmanager fails to start at boot.

The problem is with my ulimit setup. When stacksize is unlimited, then pgrep is trying to allocate too much memory.

I did some research and found that doing:
ulimit -s unlimited
brakes pgrep:
# pgrep x
pgrep: cannot allocate 4611686018427387903 bytes

It is also strange that pgrep performance depends on stack size limit.
Before psutils update it was ok.

I use custom /etc/initscript that makes my stack size unlimitted and that cuses /etc/rc.d/rc.networkmanager to fail on boot.
