[Gate-users] Problem with 'std::bad_alloc'

[Michal Knap]

Hi David,I have only one version of Gate and Geant4 installed - Gate v7.0 and Geant4.9.6.p04.
I successfully  run benchmark simulation - benchmarkSPECT, with or without visualization.
So it's somthing with my code i think. What can i disable/enable to fix this bug?
Best regardsMichał Knap

 Hi Michał,

Some more simple questions:

* Can you run macros from the example directory successfully, or do some 
of them result in this same error?


* Do you have multiple versions of Geant4 and/or Root installed? If yes, 
could you check with the following command:

ldd $(which Gate)

that your Gate executable gets indeed linked to the same versions as the 
ones you configured during installation of Gate? If the versions do not 
match: then fix your environment, or reinstall Gate (from scratch).



If these simple questions do not help, then I think the next step is to 
make a minimalistic version of your macro that demonstrates the error 
you are seeing and post it here on the list, so that other people have a 
chance to reproduce this problem. Please also specify how you run the 
Gate command (with which options).

HTH,
David Boersma
