Description Laszlo (Laca) Peter 2010-07-05 06:07:06 UTC 
When xmlStrdup or xmlStrndup fails to allocate memory it calls
xmlErrMemory, which calls __xmlRaiseError which calls xmlStrdup.
This leads to infinite recursion that eventually crashes the
process.

(Noticed during stress testing on OpenSolaris.)
Comment 1 Tilman Giese 2013-12-03 10:39:16 UTC 
A slightly similar problem with an infinite recursion between xmlNewGlobalState and __xmlGenericError (tested with 2.7.8, but still present in 2.8.0):

Comment 2 GNOME Infrastructure Team 2021-07-05 13:23:50 UTC 
GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org.
As part of that, we are mass-closing older open tickets in bugzilla.gnome.org
which have not seen updates for a longer time (resources are unfortunately
quite limited so not every ticket can get handled).

If you can still reproduce the situation described in this ticket in a recent
and supported software version, then please follow
  https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines
and create a new ticket at
  https://gitlab.gnome.org/GNOME/libxml2/-/issues/

Thank you for your understanding and your help.
