Tetgen crashes sometimes and terminates SCIRun5 #933

Open moritzdannhauer opened 9 years ago

moritzdannhauer commented 9 years ago

Is there any way to make sure if an external library crashes SCIRun5 will not be affected by it (=terminates it)?

dcwhite commented 9 years ago

It depends. There are various workarounds. Not sure we can modify tetgen code ourselves though.

moritzdannhauer commented 9 years ago

Yes, changing tetgen code would not be an option. 1) However, we could make it clear that tetgen could take literally forever to create a mesh very explicitly in the documentation. 2) Can we put tetgen or any other module that likes to crash into something(!?) like a try ... catch structure. In case a crash was detected (catch), the tetgen instance gets removed safely / all memory is given back to the system (progress bar gets to 100%).

Unfortunately, tetgen tends to segfault. I'm familiar with how to detect and report the error on Unix type systems (see http://www.cplusplus.com/forum/unices/16430/ for example), but haven't looked into Windows.

jessdtate commented 7 years ago

I found a case that crashes pretty reliably. IF there are point clouds and surfaces as input, the supress surface splitting must be checked, otherwise tetgen and SCIRun crashes with a Segmentation fault.
