[php-src] Issue #13115: make abortable zend_error when --enable-debug

Issue: https://github.com/php/php-src/issues/13115 Author: SVGAnimate ### Description when zend throws an error. it uses a bailout system to catch the exception. Example : [zend_alloc.c near line 385](https://github.com/php/php-src/blob/16c1c49f1b9153fab8fb15935ffce1c764a398ae/Zend/zend_alloc.c#L385) Sometimes the error is caught at a higher level. and we lose the call stack in gdb Example : [ext/intl](https://github.com/php/php-src/blob/16c1c49f1b9153fab8fb15935ffce1c764a398ae/ext/intl/collator/collator_class.c#L84) The abort() function stops the debugger at the point where it was called. But [abort is never reached](https://github.com/php/php-src/blob/16c1c49f1b9153fab8fb15935ffce1c764a398ae/Zend/zend.c#L1650) Do you see any contraindication to doing this kind of thing in zend.c:zend_error_noreturn ? ```C #if ZEND_DEBUG char *level = getenv("Z_DEBUG");// $ export Z_DEBUG=fatal-errors if (level && 0==strcmp(level, "fatal-warnings")) { abort();//gdb stop } #endif [...] va_end(args); /* Should never reach this. */ abort(); ``` Perhaps there is an existing solution so that the debugger stops where the error occurs?
