Comment (by ttcoder):
While trying to reproduce that infinite loop I got a crash. The code path
is suspiciously similar so I'll wait for Ingo's advice before filing a new
ticket. That "new" ticket would go something like this:
Title: daemon crashes indirecting 0x676b7068 while activating/deactivating
packages
Body: the "address" 0x676b7068 is in fact the ascii string "hpkg" so
that's an obvious candidate of memory corruption isn't it? Here's the
sequence of events (below).
Seems I have a knack for rubbing this hrev47209 the wrong way so don't
hesitate to ask me for experiments and reproducible cases :-)
