>Description:

	attempt to build pkgsrc/x11/gtk2 (gtk+-2.8.15) and get the following
compiler error:

Please submit a full bug report,
with preprocessed source if appropriate.

>How-To-Repeat:

	See above.

>Fix:

	Workaround: Compile with "-O2 -fno-gcse" instead of "-O2".
The former doesn't exhibit the problem.

Does this happen with gcc4 (either 4.1 or 4.5)?

 No idea... Unfortunately I don't have hardware readily able to test this
 any more :( 

 Later...

State-Changed-Why:
the information refers to an old gcc, old gtk2, etc., and submitter can't retest. it won't be surprising that there are still bugs, btu the current information is hard to act on.
