zend_mm_heap corrupted when running tests on Windows CI with ZTS builds

[cmb69]

Description

Apparently, all our WINDOWS_X64_ZTS CI builds trigger a "zend_mm_heap corrupted" message just after starting the test runner, e.g. https://github.com/php/php-src/actions/runs/10154549484/job/28079930149#step:6:77. This does not happen with NTS builds. I cannot reproduce that issue locally, so I have no idea what's wrong there. This is apparently not the case for PHP-8.1, but for all higher branches.

Maybe somebody has an idea what's happening, or wants to investigate this more closely.

PHP Version

PHP 8.2

Operating System

Windows

@cmb69 Please see #10838 where I analysed this.

Ah! Thank you @nielsdos! Closing this as duplicate of #10838.

Maybe #6993 wasn't the best idea.

dl() in general isn't the best idea. I remember looking into what would be necessary to make it work properly but it's a huge effort.

[cmb69]

Maybe it's best to rid dl() altogether. It appears to be of very limited use.

I've been thinking that as well, maybe 8.5 material

Yeah, deprecate in 8.5 and drop in 9.0. But if 9.0 would be next, we would have to keep it for a long time. :(

Anyway, I just forgot to press the close button again.
