pure virtual w/implementation bug in GCC 3.3?

- Subject: pure virtual w/implementation bug in GCC 3.3?
Hi everyone,
Using GCC 3.3 or GCC 3.2, it appears unable to digest this code:
--------8<--------
class Foo
{
public:
virtual ~Foo() = 0 { }
};
--------8<--------
> g++33 -c foo.cpp
foo.cpp:4: error: parse error before `{' token
foo.cpp:4: error: missing ';' before right brace
Pure virtual functions can have implementations. Pure virtual destructors (if I recall correctly) MUST have implementations.
And if the implementation is defined later with GCC 3.2 or 3.3 -- either as inline or not as inline ("out of line"?) -- it digests it with out an issue.
As per Stroustrup's C++PL, the EBNF grammar looks like it should and does support the syntax given above. (The "implicit inline" of a method given in the class declaration.)
Is this a known bug in GCC?
Or is this a new bug in GCC?
Or am I misinformed?
Thanks,
