Hello,

Please could you check the PHP code you think is triggering this issue. Looking at the call stack I can see a call to imagickdraw::setfillcolor:

"zim_imagickdraw_setfillcolor.../data/eglic/downloads/php/imagick/imagickdraw_class.c:310"

Which isn't listed in your bug report.
 [2014-09-01 05:45 UTC] eglic dot csdn at gmail dot com 
code at "zim_imagickdraw_setfillcolor.../data/eglic/downloads/php/imagick/imagickdraw_class.c:310 is:

 310     if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "z", &param) == FAILURE) {
 311         return;
 312     }
 [2014-09-01 23:14 UTC] Danack at basereality dot com 
Yes, but the PHP code you said to replicate the issue is "code crashed while new ImagickDraw();" which does not include a call to setfillcolor.

@Danack 

I found 2 strange things:

1. run this command at terminal : php -r "echo 'A';new ImagickDraw();echo 'B';"
   then php crashed and core dumped. as you see,it stoped at zim_imagickdraw_setfillcolor

2. I built a debug version with --enable-debug and try again,it's OK?!!!

Thanks for your report!

I cannot reproduce this under *stable* conditions.

Since the provided trace doesn't look like it could originate from the code you are running, it's likely that the issue lies within the unstable xdebug you have enabled, or the unstable xcache you have enabled. In order to identify if this is the case and which is the culprit, please disable these extensions and verify whether the issue occurs when they are disabled.

If it does not, enable them one at a time to determine which extension is the cause of the problem. If the problem still occurs with these extensions disabled, please provide a new stack trace generated under these conditions.

Thanks
