Thanks.

Unfortunately I found / remembered another weirdness.

Christian> -  if (linkage_name[len] != '\0')
Christian> +  if (linkage_name[linkage_name.length ()] != '\0')

This code let the caller pass in a possibly-unterminated string, and
then made a local copy with the terminating \0 in that case.

However, this was always a bad idea, and now is probably a libstdc++
debug-mode assertion failure (<- just guessing but if it isn't, it
should be!).
