FWIW, The same or similar problem appears to effect the following code:

        #include <string>

        struct bar {
                std::string s;
                int y;
                int z;
        };

        bar bar_array[] = {
                { "abc", 1, 2 },
                { "def", 2, 4 },
                { "ghi", 3, 6 },
                { "klm", 4, 8 }
        };

Which results in:

        bar.cc:14: error: conversion from `const char[4]' to non-scalar type
           `bar' requested
        bar.cc:14: error: conversion from `const char[4]' to non-scalar type
           `bar' requested
        bar.cc:14: error: conversion from `const char[4]' to non-scalar type
           `bar' requested
        bar.cc:14: error: conversion from `const char[4]' to non-scalar type
           `bar' requested

Unlike the privious example, this one can't be worked around with an
extra layer of {}'s.

And since I neglected to mention it before, this is a g++ from the CVS head,
on QNX 6.2 (the changes I submitted for QNX in August with slight tweaks as
suggested by Zack and as necessary to to adapt to the CVS head.
