>Description:
When compiling the attached test-case source:

> gcc -O3 -c ise_56.cxx 
ise_56.cxx: In member function `virtual long unsigned int Pipe::ewrite(const 
   void*, long unsigned int)':
ise_56.cxx:55: Internal error #56.
ise_56.cxx:55: Internal compiler error in resolve_offset_ref, at cp/init.c:1963

The same small test source compiled with "-O2" instead of
"-O3" works fine, so I assume the new inliner is the cause
of the problem.
>How-To-Repeat:

>Fix:
small rearrangements of the code let the bug disappear,
e.g. replacing

(Writeable::blocking_mode)

by 

(Writeable::blocking_mode == true)

That of course is an ugly workaround, only... :-)
