Short description of error

All tests with --debug --factory-startup

Memory errors in cache handling cause Blender to crash

Main system:
Calloc returns null: len=35389440 in imb_addrectImBuf, total 3606303772

Lenovo X220:
Error: Not freed memory blocks: 3, total unfreed memory 0.000626 MB
reconstruct len: 104 000000000FA59DB8
reconstruct len: 104 000000000FA59C38
reconstruct len: 120 000000000FA59AB8

Exact steps for others to reproduce the error

--factory-startup
Open:
{F8376452}
Play Animation
Increase Sequencer memory limit
Crash

I can get it to consistently crash by filling up the cache; say 4 gigabytes, whilst playing the animation slowly increase the sequence cache limit, after a couple of seconds, crash

Will try to find more reliable repo steps as @iss and I could not reproduce consistently...
