Yes, indeed I have -- a typo on my part.

Note, however, that this line (line 7 of my code sample) compiles
properly (even with the error).  (It turns out that {-7-8-9} initializes the
vector that is a piece of the larger structure to {-24}, i.e., a vector of
length one with vec[0] = -24.)

Fixing the typo produces no substantive change:  Line 8 (the test of
vector-of-vector-of-pair) still fails to compile with mingw32 4.5.0, but
does compile with mingw-w64, 4.5.2.

Thanks for the catch.
