From: craig dot mohrman at oracle dot com Operating system: Solaris 11 PHP version: Irrelevant Package: opcache Bug Type: Bug Bug description:Zend Opcache on Solaris 11 x86 needs ZEND_MM_ALIGNMENT=4
Description: ------------ This is a place holder bug for anyone working with Solaris and php 5.3.27 I haven't tried the latest version of PHP so maybe this just goes away. I've documented this in a thread here: https://github.com/zendtech/ZendOptimizerPlus/issues/122 But the problem appears to be in php itself. This is compiling the Zend Opcache 7.0.2 from: http://pecl.php.net/package/ZendOpcache When compiling ZendOpcache with php 5.3.27 on Solaris 11 x86 with the Solaris Studio compiler (12.1) I'm seeing Overflown errors even with the most trivial of php programs. This is all being done in 32-bit. Sparc has no such issue. Works out of the box. As a workaround I'm patching ZEND_MM_ALIGNMENT: #define ZEND_MM_ALIGNMENT 8 #define ZEND_MM_ALIGNMENT_LOG2 3 to #define ZEND_MM_ALIGNMENT 4 #define ZEND_MM_ALIGNMENT_LOG2 2 over in PHP/Zend/Zend.m4 and everything works fine. I got this 4 when compiling php 5.3.27 with gcc 4.5. That comes up with ZEND_MM_ALIGNMENT=4 but when compiling with Solaris Studio I get ZEND_MM_ALIGNMENT=8. Oddly on Solaris sparc both Solaris Studio and gcc 4.5 come up with: ZEND_MM_ALIGNMENT=8 but that works fine. So see the actual patch below. This is not the solution but gets Zend Opcache working on Solaris x86. Test script: --------------- $ cat simple.php <?php function m_x_plus_b($m, $x, $b) { return $m*$x+$b; } $slope=1.5; $x=2; $b=3; echo "y = ".m_x_plus_b($slope,$x,$b)."\n<br>"; ?> Expected result:
