Another bug using RH7.0 version of g++...

[Fons Rademakers <Fons dot Rademakers at cern dot ch>]

Here another g++ bug. Note this bug only appears with -O2. It compiles and works
fine with -O.

-D_REENTRANT -o histpainter/src/THistPainter.o -c

In the attachement the .ii file.

Did anybody test this compiler before making it the default of RH7.0?!?


Cheers, Fons.
