Description Tomas 2018-03-06 13:23:14 UTC
In 'xmlregexp.c' at line 545 a condition is evaluated to handle the error in the case of failed allocation of "transitions". However, the statements in the "if" that handles the error do not free each element in the "stringMap" array as the others similar "if" are doing e.g lines 520, 531, 603.

If the condition at line 545 becomes true then the elements in "stringMap" wouldn't get freed and that would result in a memory leak. Unlikely, but possible.

Can you provide more detailed information? For example, the version number, the specific content, whether it has been fixed now?
Comment 2 GNOME Infrastructure Team 2021-07-05 13:22:03 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.
