 But what exactly is going on here?
 
 I was pointed at exception.cc in external/bsd/libc++/dist/libcxxrt/src,
 which includes apparently proper #if to select the throw() vs. the
 non-throw() variant - but the line numbers cited here do not match
 and it is unclear what happens in the concrete build.
 
 So: what do the lines (including a few lines above/below) look like in
 the failing build? And what obscure build options are in effect?
