Simple call such as object->do_something()

Well I will try to find the time to extract a test case.

I've had very wierd reactions from egcs on this code (20K+ lines of very
compact code with lots of templates and stuff). It's always been bugs in
the code (that's what you would expect) but I'm stumped on this one.

The code was originally compiled with gcc 2.6.3 with extensive usage of
templates and absolutely refused to compile either under gcc 2.8.1 or egcs
1.x without lots of changes to the code (changes which have been made).

It still refuses to compile with non gcc based compilers :-)

Thanks for your help,
Gilles
