Crash on debugging

[john-terraspace]

As soon as a breakpoint is set in the node.js process the native canvas module crashes with the following error:

---

Microsoft Visual C++ Runtime Library

Assertion failed!

Program: ...s\canvas-prebuilt\canvas\build\Release\canvas.node
File: c:\projects\node-canvas-prebuilt\no...\nan_obj..._wrap.h

I found this:
nodejs/node#15099

which seems identical, yet this still seems to be occurring. I've tried building canvas myself directly and the same occurs.

See Automattic/node-canvas#855. The fix was merged but it hasn't been released yet.

I see that bug was last commented on in Dec 2016 ??? / then a confirmation in July. It seems to related to 1.6.6, while the release is now 1.6.7
Is there a way to install a later/possibly alpha version like 2.0 ?

Grabbed a copy of this branch, and rebuilt, seems to fix it.

@john-terraspace all of the releases listed on the releases page are in npm -- npm install [email protected] for example.

Thanks for that, I'll remember that in future, the custom build worked perfectly, just need it for debugging purposes anyway and will switch to the normal release once done.

Thanks
