Template Processor document size limit ?

[nsasit]

Describe the Bug

I use a complex word document as template.
I use $templateProcessor->cloneBlock('device', 0, true, false, $array_devices); where array_devices is a array.
It's work fine but if I add some paragraphs to my template (only text), I does not work.
Seems to be a problem of max size of my template because if I remove some characters, it's work fine.

Steps to Reproduce

$templateProcessor->cloneBlock('device', 0, true, false, $array_devices); with my word template => does not working
If I edit my template and remove some characters (only text, not special characters, no image, no variable ...) => works

@nsasit what was the fix for this? I'm having a similar issue whereby a template of >8000 words with some formatting seems to break but removing some words fixes it.

Edit: I tried changing upping the memory_limit in php.ini but it did not make a difference.

Ah bingo, the fix was to up the pcre.backtrack_limit and pcre.recursion_limit since preg_match was silently failing with large strings.

Found this Stack Overflow question which helped find the issue.

Thanks a lot !
You saved my life !
note for others : pcre.backtrack_limit and pcre.recursion_limit works
DO NOT turn off pcre.jit : result in not working at all for bloc replace/clone
