Subject: PHP allocating too much memory
From: peterlebrun@gmail.com (Peter LeBrun)

Hi -

I'm getting the following error in php7.0.5:

Fatal Error: Allowed memory size of 536870912 bytes exhausted (tried to
allocate 140729445144864 bytes)

If it's relevant, we're using dblib+freetds.

I can't reproduce the issue deterministically; the best I can do is to
repeatedly curl an endpoint and something like 30% of the requests will
fail due to the above error.

The weirdest part about this is that PHP is somehow trying to allocate
140TB of memory.

Has anyone seen anything like this?  Any insights would be appreciated.

Thanks,

Peter
