Strange fatal error

[qwtel]

I'm sometimes getting the following error:

#
# Fatal error in , line 0
# Check failed: allocator->SetPermissions(reinterpret_cast<void*>(region.begin()), region.size(), PageAllocator::kNoAccess).
#
#
#
#FailureMessage Object: 0x16b2f0428

I've compiled a minimal example here: https://gist.github.com/qwtel/d2728ea41a48f7168bc68cd4785de574

It seems to be related to the use of async and has some race condition-like properties: The queries succeed a random number of times, but usually not more than ~10

I'm getting this with other wasm modules as well, so I now assume this is a bug in either deno or v8...

Question out of curiosity: Are you running this on the new apple M1 chipset?

[qwtel]

Yes, I was using the ARM version on a M1 mac. I've switched to the x86 version shortly after I wrote this, and it fixed the problem in both wasm modules I've tried. Hopefully something that get's ironed out over time... Seems to be fixed in Deno 1.8
