>Description:
The current mainline gets an ICE compiling the attached test
case, extracted from the Qt application development toolkit.
With no compilation options other than -c, the output is:

qtbug.cpp: In function `void foo()':
qtbug.cpp:20: error: uninitialized const `r0'
g++: Internal error: Segmentation fault (program cc1plus)
Please submit a full bug report.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

I haven't tested Qt regularly with the mainline so I don't
know how long it's been failing.  It passes with GCC 3.1 and
with the current 3.1 branch.

If "const" is removed from the definition of "member" then
the file compiles successfully.
