it seems like freebsd 11.1 stock llvm40 compiler is the issue.

gcc6 from ports has the same issue but the coredump is different.

llvm38 and llvm50 from ports produce php binaries that do not segfault:

# cat hh.php 
<?php datefmt_create('en',1,1);
# for a in /usr/local/php-7.2.1-gcc/bin/php /usr/local/php-7.2.1-clang38/bin/php /usr/local/php-7.2.1-clang50/bin/php /usr/local/php-7.2.1-clang40/bin/php; do echo ${a}; ${a} hh.php ; done

/usr/local/php-7.2.1-gcc/bin/php
Segmentation fault (core dumped)
/usr/local/php-7.2.1-clang38/bin/php
/usr/local/php-7.2.1-clang50/bin/php
/usr/local/php-7.2.1-clang40/bin/php
Segmentation fault (core dumped)

Interesting. Need to check how ports compile it though because I don't remember it using an external compiler.

Is this still an issue with any of the actively supported PHP
versions[1]?  If so, it still looks like a compiler issue, doesn't
it?

I haven't seen the error recently so I think it's okay to close this.

Thanks for the swift reply!
