The GC is currently not reentrant, thus we can't allocate during finalization. If an exception is thrown in a finalizer, it will allocate a TraceInfo object, even if the exception was preallocated.

Same goes for onOutOfMemoryError which is even marked as @nogc, even though the trace is allocated using the GC.

We should require http://dlang.org/library/core/runtime/runtime.trace_handler.html to be @nogc. For a deprecation phase we could still accept allocating trace handlers, but not call them in @nogc errors like onOutOfMemoryError.
