Hindsight is 20/20, but don't use assert in dtors:
https://github.com/dlang/druntime/blob/f94e816c1dd229cbb133085a6fc41d1bd6d45594/src/core/exception.d#L447

Turns out it's already filled: https://issues.dlang.org/show_bug.cgi?id=7349

v2.097.0 will come with a fix for this, leaving open for now as it's not yet released (and until it's the oldest supported release).
