 Hi

 Today I finally decided to upgrade to macOS Mojave and re-install all the
 ports I need.

 I still have to support various projects running on PHP 5.5 unfortunately,
 and I noticed it no longer properly works on Mojave when php55-opcache is
 installed and enabled.

 My setup is with Apache 2.4 => php55-fpm => php scripts[[br]]
 CLI-wise, everything is fine. But when attempting to open a php script
 through the webserver, it crashes.

 The php-fpm.log says
 {{{
 [23-Feb-2019 18:27:19] WARNING: [pool www] child 95563 exited on signal 11
 (SIGSEGV) after 3.393581 seconds from start
 }}}

 Here's part of a crash log I found in /Library/DiagnosticReports:

 It appears this is a know problem in Homebrew and FreeBSD and already got
 fixed in those projects:
 - http://openbsd-archive.7691.n7.nabble.com/clang-6-php-5-6-broken-with-
 opcache-td341170.html &
 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227723
 - https://github.com/Homebrew/homebrew-core/issues/32434 (fix:
 https://github.com/Homebrew/homebrew-
 core/commit/67cdb1180bf7aaddf7a22135f5fc9011964b783f)


 I have this problem on PHP 5.5, but it might as well occur on 5.6 or 5.4
 and 5.3 (I haven't tested these).
 On PHP 7.0, 7.1 and 7.2 it does not occur.



 Any chance a fix can be included in Macports for this problem?

 I would totally understand if this gets closed without resolution, as PHP
 5.x is no longer supported.[[br]]
 We can work around the problem by disabling the opcache module in PHP.
 Just posting this to see if there is interest or maybe for other people
 who run against the same problem so they can find a solution quicker.



 Thanks!
