With libxml2-2.12.0 and perl-5.38.0 t/44extent.t failed:
|
||||
|
||||
$ perl -Iblib/{lib,arch} ./t/44extent.t

Entity: line 1: parser error : Char 0x0 out of allowed range

Entity: line 1: parser error : PCDATA invalid Char value 0

# Looks like your test exited with 2 before it could output anything.
|
||||
|
||||
The cause was xmlParserInputBufferCreateMem() which does not copy a supplied
|
||||
buffer. A string returned by the ext_ent_handler handler. As a result, libxml2
|
||||
read from a deallocated memory parsing random garbage.
|
||||
|
||||
This patch fixes it by copying the string with
|
||||
xmlParserInputBufferPush().
