However, the isolated string offset error alone does not trigger the crash, it
gets stack-traced correctly by my error handler.
The same error inside a stack of method calls triggers the issue. Unfortunately
I
haven't been able to isolate a minimal code that will let you reproduce the
issue, I do can reproduce it 100% systematically but with complex code +
database
and complicated sequence of steps of which I have no idea what is relevant to
the
issue.

I'll try to post the error handler replacing the [at] character with [at] (you
get what I mean), let's see if that is what bothers the antispam...
set_error_handler(function($errno, $errstr, $errfile, $errline){
http_response_code(500);
header("Content-Type: text/plain");
$backtrace=debug_backtrace();
$output="$errstr \n [at] $errfile($errline)\n";
foreach ($backtrace as $i=>$item) {
if ($i>0) $output.= "#$i. [at] ".$item['file']."
(".$item['line']."): ".(isset($item['class'])?
$item['class']:'')."::".$item['function']."(".(is_array($item['args'])?
[at]implode(",",$item['args']):'').")\n";
}
die($output);
});

And you definitely do need to see it before you can say what you are saying

No man, my error hanler sends a 500 AND prints a stack trace.
I've had thousands of errors in my code before, and my error handler correctly
printed a stack trace.
And if there was an error in my error handler, then the PHP error should be
normally logged in the error_log. NOTHING is logged in the error_log, that
seems
to indicate PHP is crashing.
No matter how bad is my error handler, if it crashes PHP there's a bug in PHP

There is no bug. Your custom error handler is explicitly sending a 500. We do
not
need to see it.
