Bug #71955 [NEW]: shmop_open: creating infinite amount of segments

From: kakkau at grr dot la Operating system: PHP version: Irrelevant Package: PHP Language Specification Bug Type: Bug Bug description:shmop_open: creating infinite amount of segments Description: ------------ 1. Run shmop_open with $key=0 and $flags="n" multiple times. 2. Wonder about a missing warning when using the same key for creation. 3. Check the output of ipcs -m. There should show up multiple segments now. For other integers <> 0 shmop_open works as expected Test script: --------------- <?php $res = shmop_open(0,"n",0600,1024); $res = shmop_open(0,"n",0600,1024); ?> Expected result: ---------------- At least a warning should be thrown w/o creating another segment.
