Description:
------------
I can trigger the following assertions...

Assertion failed: (phi->use_chains[pred_offset] == ((void*)0)), function zend_ssa_remove_phi_source, file /Users/chrisgraham/dev/php-7.2.0/ext/opcache/Optimizer/zend_ssa.c, line 1282.

Assertion failed: (op_array->opcodes[def].result_type & ((1<<1)|(1<<2))), function dce_live_ranges, file /Users/chrisgraham/dev/php-7.2.0/ext/opcache/Optimizer/dce.c, line 590.

Assertion failed: (op_array->opcodes[b->start].opcode == 70 || op_array->opcodes[b->start].opcode == 127), function zend_ssa_remove_nops, file /Users/chrisgraham/dev/php-7.2.0/ext/opcache/Optimizer/dfa_pass.c, line 165.


I can't narrow this down to a test case, but I may be able to help you reproduce it.

Download getid3, and do a mass lint operation...

find . -name "*.php" -exec php -l {} \;

Hopefully you'll reproduce and see assertions scattered in it.
Linting the individual files scanned before or after the assertion doesn't seem to cause it, so I guess it is either concurrency related, intermittent, or has some kind of delay effect (but really I don't know!).

I can't reproduce this. My guess is that this has already been fixed by https://github.com/php/php-src/commit/b6294bbc6cfc4f8fb23a2c7f2d18cbd85001c056. Can you check whether the current PHP-7.2 resolves this for you as well?

I tested on git HEAD of the day I submitted the bug (much newer than this commit) and PHP 7.2.0.

To double check I tried again on both (after a git pull and make)...

Maybe it is Mac-specific somehow.
