Hi Igor,
I recommend you update to
07-04-23 21:14 13,531,108 76 php-7.4.32-os2-debug-20230705.zip
from
https://smedley.id.au/tmp/php-7.4.32-os2-debug-20230705.zipThis build matches the current sources at
https://github.com/psmedley/php-7-os2which will make your exceptions easier to analyze.
The php sources contain lots of static functions which do not always get encoded into the HLL debug data as well as one might wish.
This means you have to map from the source line numbers to the actual functions by. The following is the actual call path that triggered the exception:
<pre>
Trap -> BA9EC001 PHP7 0001:009AC001 zend_alloc.c#2189 _format_httpd_os2_timestamp + 718 0001:009AB8E9 (U:\dev\php-7-os2\Zend\zend_alloc.c)

0012FA88 BA9913E4 PHP7 0001:009513E4 TSRM.c#443 _ts_allocate_fast_id + DC 0001:00951308 (U:\dev\php-7-os2\TSRM\TSRM.c)
</pre>
When debugging, I recommend using idebug and setting both StartServers and MaxThreads to one. It makes the running under idebug a lot easier.
Also, if you are not familiar with idebug's child debugging feature, you will need to learn to use it since you will be
debugging the child httpd process in most cases.
