Summary

0030763: Behavior change between the Node wrapper from OCCT > 7.2.0 and 7.1.0

Description

Hello,

Using the node-occ wrapper for Open Cascade I noticed that with the same complex geometries I have everything working properly with occt 7.1.0.

Using version occt 7.3.0. I get a 'Process finished with exit code -1073741819 (0xC0000005)' on node (all version) Windows and the correspond segmentation fault with core dump (I can provide you the dumped cores for more details).

Nothing else changed, So I suppose something is broken from 7.1.0 to 7.3.0 ?

Any information would be nice.

Regards,

Steps To Reproduce

Unfortunately I can't provide you the 3d models.

What I can do:

dump cores from Linux with OCC built in debug mode.

Additional information
and documentation updates

The library I used is this one: https://github.com/antonymarion/node-occ/tree/testOCCT7.2.0 [^]

I created the branch testOCCT7.2.0

you can install it with npm using "node-occ": "git+https://github.com/antonymarion/node-occ#testOCCT7.2.0" [^] in your package.json
