`RegEx.search_all` causes 'Condition "p_ptr == nullptr" is true.' error with PCRE2 10.42 (Linux distro packages)

[Selenyhr]

Godot version

v4.0.2.stable.arch_linux

System information

ArchLinux rolling, Linux 6.2.11-arch1-1. Vulkan Mobile on RX 6900XT

Issue description

When using RegEx.search_all, an error is added to the log:

ERROR: Condition "p_ptr == nullptr" is true.
at: free_static (core/os/memory.cpp:148)

The number of triggered errors seems to be affected by the number of matches the regex makes.

Steps to reproduce

Have any script that does something using RegEx.search_all:

var regex: RegEx = RegEx.new()
regex.compile(".")
regex.search_all("test")

The above example will trigger 5 error messages (1 per match + 1 fixed).

Minimal reproduction project

minimal_project.zip

Script was made for running through CLI:
godot --headless -s new_script.gd

I know you are on linux, but I'm just adding a data point in case others are checking this bug.

No repro on current master on macOS.

The error is likely triggered when _regex_free is called in regex.cpp.
This calls Memory::free_static(void *p_ptr, bool p_pad_align) which checks for the p_ptr == nullptr.

I get the same error upon calling RegEx.sub.
OS is also Arch Linux.

arch build is using system pcre2, which is at version 10.42
That version seems at the moment slightly incompatible with godot.
#70472 is in progress to fix compatibility with 10.42

I'm not sure if the only effect of this bug is the error message. I opened arch bug as well, just in case this issue might have other consequences. (https://bugs.archlinux.org/task/78428)
