Thank you for the report!
I relayed this ticket to our JIRA: https://jira.mongodb.org/browse/PHPC-555 for better tracking.

I haven't tried your reproduce case yet, but it doesn't appear to be using the MongoDB extension so I'm curious if you can share you configuration? Or does this always happen using the example above as long as the MongoDB extension is loaded? That seems a bit strange :)

The error log you attached definitely indicates a problem in the MongoDB extension

i found when i use jemalloc (4.0.4), mongodb will occurs error, please check!

I've since released 1.1.5, which I believe may fix this issue if it is a duplicate of #209. It's possible that the backtraces differ as a result of using jemalloc instead of Zend's memory manager; however, I expect the root cause may be the same. I will leave it open for you to confirm.

Note that the patch is only able to resolve the problem when libmongoc is bundled (i.e. statically compiled) with the driver. If libmongoc is loaded as a system library, that will rely on an upstream fix (see: CDRIVER-1165).

thanks, fixed with 1.1.5
