Assert when collecting backtraces

[Jasper-Bekkers]

When store_stack_traces is on (which it is by default) we occasionally get a crash in the backtrace crate. It would seem we're asserting in this line: https://github.com/rust-lang/backtrace-rs/blob/47069af003d7f4ca62f5b4517a43039c46dfc34d/src/dbghelp.rs#L315

OS Version: windows None (None)
Report Version: 104


Application Specific Information:
assertion failed: `(left == right)`
  left: `128`,
 right: `0`

Small note: we should probably default to having stack trace collection being off by default.
