not really, more a lack of practice than anything else.

My top prio for this year, write a doc  about backtrace, coredumps and
the likes for win, maybe some tools to automate the whole things :)

with opcache, and perf related crashes, it is better to store the core
dumbs and do a post mortem analyis (can be done anywhere then, from
windbg or VS).

See https://bugs.php.net/bugs-generating-backtrace-win32.php to at
least generate a backtrace :)
