Description

I am not completely sure about the cause, but I have come by a strange behaviour by some templates (e.g. http://commons.wikimedia.org/w/index.php?title=Image:Policarpa_Salavarrieta_2_pesos_Oro.jpg&oldid=8606384). After a bit of playing, I was able to create a quite simple reproducible test case (see the URL at this bug report):

The result: strangely broken rendering.

(I am not sure if the bug is in the parser proper, or in the ParserFunctions.)

Version: unspecified
Severity: normal

• bzimport raised the priority of this task from to Medium.Nov 21 2014, 9:59 PM

• bzimport set Reference to bz12488.

• bzimport added a subscriber: Unknown Object (MLST).

Looks fine in the new preprocessor:

This is an old bug, it's due to double-parsing during template expansion, $noparse=$noargs=false in braceSubstitution(). Probably a duplicate report.

Oh yes, I have (maybe) found it (even though I tried to find it before reporting, unsuccessfully…). Wouldn’t it be bug:5678?
