Stack corruption error on MacOS

[jvergeldedios]

I can't seem to find a pattern, but I intermittently get a stack corruption error that crashes my node process with a SIGABRT. I went into the console and found the following backtrace:

It looks like it's happening in the Peripheral::GetManufacturerData method. I tried to add logging to see if anything would come out at the beginning of the method before the stack corruption occurs, but nothing was logging. I also tried updating SimpleBLE since the backtrace mentions simpleble.node to 0.9.0 and 0.8.1 but the behavior remains.

Relevant version info:
webbluetooth: 3.2.1
MacOS: 14.5

Edit: Other relevant information: I'm attempting to connect to several devices simultaneously which I've noticed can trigger other issues elsewhere in the library. Potentially a race condition of some sort or maybe multiple devices clobbers values in the stack for some reason?

Never mind on the multi-device theory. I've seen it happen with a single device multiple times now.

I'm keen to know if this is an issue with SimpleBLE or this wrapper. Do you have any data on whether this issue occurs if using SimpleBLE directly?

[jvergeldedios]

I haven't tried that. I'll see if I can find some time to create a minimal reproduction of both and link it here.
