spamming with "Warning: not enough memory, new stack ..."

[Max Alekseyev <maxale@gmail.com>]

Hello!

While I was running a long computation in GP (with rather stable
allocation of memory), another process has eaten all system memory and
got killed by the system. That has some weird effect on the running GP
- it started printing messages like quoted below over and over again
(long after the incident with the system memory). From time to time
these messages are interveawed with the messages I expect from the
computation, so my hope is that the computation itself is not
affected.

...

Is this an expected behavior? Why the stack goes up and down by
itself? (my program does not make any stack reallocations)
