[package_daemon] crashed while running haikuporter

[diver]

hrev47361 gcc2h.

Had a mounted chrooted volume (left from building this package before) which haikuporter couldn't unmount: unmount: unmounting failed: Device/File/Resource busy

I force unmounted it with: unmount -f /data/haikuports/sys-libs/libexecinfo/work-1.1/boot/system

Then I ran haikuporter libexecinfo and a second later package_daemon crashed.

Replying to diver:

A while back I added printing more diagnosis info (the open FDs) for this case. It would be nice, if you could create a ticket with the info attached when you encounter it again.

Regarding this issue, it apparently is a heap corruption. Given that there's at least one other ticket (#10898) that suggests some heap corruption issue, I hope sifting through the Coverity issues will turn something up.
