What steps will reproduce the bug?

I unfortunately don't know. This happens occasionally in a complex application and I don't have found any way to trigger the bug. It just happens sometimes.

What happens?

The native code crashes. See here for the sentry stack trace: https://sentry.internal.makepro-x.com/share/issue/00c398c251ff426db2063a206d9117a1/

I know that this error comes from node-serialport, because if I open 37a99351-6a52-4763-a2d4-6ab1040c4070.tmp.node in a text editor, I find ascii text like node-serialport:DrainBaton or D:\a\bindings-cpp\bindings-cpp\src\serialport.

Unfortunately, I don't have more information available. Is there a place where I could get the .pdb files in order to upload them to sentry?

What should have happened?

It should not crash :-)

Could this be the problem?
Electron and the V8 Memory Cage

Sharing info over here too, the memory cage is enabled in electron 21 not 20, so wont be at fault here.
I did look over the native code, and didnt see the broken pattern, so I think this module should be ok.

Additionally, when hitting the memory cage issue it is very clear why it crashed:

[824319:0924/182105.427206:ERROR:node_bindings.cc(146)] Fatal error in V8: v8_ArrayBuffer_NewBackingStore When the V8 Sandbox is enabled, ArrayBuffer backing stores must be allocated inside the sandbox address space. Please use an appropriate ArrayBuffer::Allocator to allocate these buffers.
