[psumbera]

Description

Starting Apache with libphp imediately ends with core dump:

httpd:core> $C
    7fdd8f067660 libphp8.1.so`sapi_register_post_entry+0x31()
    7fdd8f067680 libphp8.1.so`sapi_register_post_entries+0x2a()
    7fdd8f067690 libphp8.1.so`php_setup_sapi_content_types+0x10()
    7fdd8f0676e0 libphp8.1.so`tsrm_update_active_threads+0xb0()
    7fdd8f067720 libphp8.1.so`ts_allocate_fast_id+0xe3()
    7fdd8f067760 libphp8.1.so`php_apache_server_startup+0x6c()
    7fdd8f0677b0 ap_run_post_config+0x54()
    7fdd8f0678f0 main+0x1873()
    7fdd8f067900 0x465fc4()

This worked well with PHP 8.1.0.

@dstogov, since you committed 72f8dbb , could you please have a look at this?

[cmb69]

FWIW, there is no issue on Windows. @psumbera, did you make sure that all used extensions have been recompiled (or better yet, don't use any shared extension)?

[github-actions]

No feedback was provided. The issue is being suspended because we assume that you are no longer experiencing the problem. If this is not the case and you are able to provide the information that was requested earlier, please do so. Thank you.

[psumbera]

All PHP bundled extensions were recompiled. This is how we build it:
