Subject: [ruby-core:115795] [Ruby master Bug#20072] free(): invalid pointer when compiled with --enable-shared --with-jemalloc

Issue #20072 has been updated by misdoro (Mikhail Doronin).

File config.log added

Hi Nobu, you will find the config.log attached.

Debugged it a bit deeper, it boils down to running `irb` and running `require 'sassc'`
that is immediately crashing:
```
$ irb
irb(main):001> require 'sassc'
free(): invalid pointer
Aborted
```

Bug #20072: free(): invalid pointer when compiled with --enable-shared --with-jemalloc
https://bugs.ruby-lang.org/issues/20072#change-105739

* Author: misdoro (Mikhail Doronin)
* Status: Open
* Priority: Normal
* Target version: 3.3
* ruby -v: ruby 3.3.0dev (2023-08-17T01:57:09Z test 5bb9462285) [x86_64-linux] 
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN
----------------------------------------
When ruby is built with `--enable-shared --with-jemalloc` on Linux (current Gentoo, ubuntu22 in docker),

running a rails app yields:
```
free(): invalid pointer
Aborted
```

The issue started appearing after 5bb946228550c7f171c27725860b153a675404f3 https://github.com/ruby/ruby/commit/5bb946228550c7f171c27725860b153a675404f3

Related to https://bugs.ruby-lang.org/issues/18409 (workaround to LD_PRELOAD jemalloc from that issue works)
