Yes, but now its a fixed bug :-)

I have just checked in a new c.bnf and semantic-c.el in the branch v1p4
which fixes parsing bugs like these.

Just get the new semantic-c.el from the cedet CVS (branch v1p4!!) and
test it. If you use semanticdb then you must delete the cache-files before!

For the cedet-developers: I have alos checked in a new test.cpp in v1p4 and
i have also checked all the output of semantic-test-all-token->text-functions
if it still correct after c.bnf changes --> it is :-)

Suggestion:
What about a function which runs for every token in a file 
semantic-test-all-token->text-functions and puts the whole output for
this file in file which then can be used a reference.

After grammar changes we just run the new grammar/parser against the
test-files, call the new output-generate-function and do then a diff
between the new output of the new parser and the old reference-output-
file ---> would be an easy, fast and save way to ensure that changes
do not damage something what was working ok before the changes.

IMHO regression-able tests are very valueable!!

Should not be hard to write such a function.......

Cedet-guys, what do you think?
