Subject: [PATCH] CGI/FPM process could crash when using libxml, fixes #61557
|
|
|
|
Since d8bddb9665637d96f20dc4a2ae5668ba376f3b17 some SAPI would only setup/reset
|
|
callbacks to libxml once, instead of for each request processed. However, this
|
|
also included a callback for structured errors, which should remain per request
|
|
(as it can be defined through PHP's libxml_use_internal_errors).
|
|
|
|
As a result, after the internal handler was set in a request, processing another
|
|
request would result in the handler being triggered while the memory associated
|
|
with it (LIBXML(error_list)) had been free-d/reset, leading to the process
|
|
segfaulting.
|
|
|
|
This reset the handler for structured errors after each request.
|
|
|
|
(see #61325 also possibly the same bug)
