>Description:
The program below does not compile with gcc version 3.2 20020424

vanuatu->g++ toto.C
toto.C: In copy constructor `A::H::H(const A::H&)':
toto.C:13: `const' qualifiers cannot be applied to `A&'

Remove the line with virtual and everything suddenly becomes fine. Something there is inconsistent. It worked with the 3.0 series and with 3.1 20011022 (experimental). In my opinion, the program should be valid, confirmed by my reading of the C++ standard (12.8.5).

I do not have access to a current 3.1 version.
>How-To-Repeat:
Just compile the code in attachment.
>Fix:
Remove the pure virtual declaration.
