Thank you so much for your reply!  I really appreciate it.

Although I remember reading about this issue at some point in the past, 
I have used std::wstring under MingW-gcc for quite some time now with no 
problems.  If it were really 100% incompatible I would wish it would 
give a compilation error!  I wonder why it crashes under the 'ireplace' 
algorithms but not the 'replace' ones -- especially since I remain 
strictly within Unicode Plane 0 (basic 2-byte characters in UTF-16/UCS-2 
which fit in a single wchar_t on Windows).

In any event, if you have any further insight here I would be interested 
to hear it, but I suppose I will just have to change compilers.  Thanks 
again!
