tls: out of memory on large write

Here's the stack trace:

/usr/local/bin/node[833]: ../src/env-inl.h:899:char* node::Environment::Allocate(size_t): Assertion `(ret) != (nullptr)' failed.

Version: v12.16.1 (installed via apt using the NodeSource repository) and v12.9.1 (using the binary from nodejs.org)
OS: Ubuntu 18.04.3 x64

It does not seem to happen running 12.9.1 on macOS 10.15.3. My best guess is that (in my code at least) the aws-sdk library is triggering it when uploading a large file. I'm not sure how to debug further; I don't really know what to do with this crash log. Will try to get that NODE_DEBUG_NATIVE=tls log if it helps.

This is NodeArrayBufferAllocator::AllocateUninitialized(size) failing to allocate the requested memory.

The error message could be better, perhaps it should even be a run-time JS exception.

Seeing that this is a bug report for an out-of-support release line and no similar reports have been received for newer release lines, I'll go and close this.
