Hi! I'm running an electron app, that loads native application (using ffi) that renders content into a canvas in electron. This native C++ code has an embedded V8 inside it. I'm compiling V8 into dynamic libraries (.dylib files) (use_component_build is set to true).
My issue is that the V8 inside Electron seems to clash with my V8 instance (they are not the same version), but only on macOS. If you look at the call-stack below of the segmentation fault, you can see that it begins in *libv8.dylib*, but ends up somehow in *libnode.dylib* which I can't really explain.

Electron version I'm using: 1.8.8 V8 versions I'm using in my app: 7.2 (I tried it with 7.8 too but with the same results) Could anyone help me out how to avoid this? -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
