[Gate-users] Problems with Gate7.0 on MacOS

[Dávid Völgyes]

Hi Paola,

Try to disable the verbose output of the random events.
There is a bug in the Geant4 (actually, in the embedded CLHEP) inside
the Mersenne Twister random number generator. Depending on actual
compilation differences, sometimes it does not cause any problem, like
in the vGATE, and sometimes it does. The code tries to read 625
elements from a 624 long array. If there is another data after this
array, then it's fine. If there is code there, then you get a
segfault.

So first, try to remove this line from the benchPET.mac:
/gate/random/verbose 1
if you still get segfault, then it is another bug, and please, report it.

Mac compilation: don't have Macs, but in worst case you can run the
vGate in a virtual machine on Mac, or a dockerized version of Gate.
(Which also runs in kind of a virtual machine.)
https://docs.docker.com/installation/mac/

Cheers from Oslo!

David
