| Re: spamming with "Warning: not enough memory, new stack ..." |
Dear Bill, Thank you for clarification! Indeed, I used the pthread version. Can this warning message be made a bit more specific to indicate that it's related to threads? (It was very puzzling for me.) Also, is there a way to suppress such warnings? Thanks, Max On Thu, Feb 22, 2018 at 7:05 PM, Bill Allombert <Bill.Allombert@math.u-bordeaux.fr> wrote: > On Thu, Feb 22, 2018 at 09:00:35AM -0500, Max Alekseyev wrote: >> 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.
