      Description

      The phase plane is making TVB to crash when using the Generic2DOscillator. I think there is an issue with numexpr.
      When I change some parameter (time integration step for instance, then I get the message "Service unavailable", which means TVB stopped).

      The error when this happens is the following:

          • Error in `/home/tvbadmin/TVB_Distribution/tvb_data/exe/python': double free or corruption (out): 0x00007f24e000c0b0 ***

      To avoid this fatal error, sometimes it works to remove all trajectories and only then change the param value. But this doesn't always help.

      Other models do not produce this behaviour (not all are using numexpr).
