I'd suggest to observe for a week or two and backport into 7.4+ if it goes ok. Thanks.

The offending commit is https://vcs.pcre.org/pcre2?view=revision&revision=1302 It'd be still better if it were fixable on our side, as 10.37 is already out. I'll see for that.

It does not reproduce with -d pcre.jit=0, so this is clearly a PCRE JIT bug. Assigning to @ab as he did the upgrade of the bundled version, but in the end this will need an upstream report and fix. ------------------------------------------------------------------------ [2021-06-03 14:40:21] Danack at basereality dot com As a simple thing to check, please could you set ini_set("pcre.jit", "0"); to see if that makes any difference on the broken version. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
