State-Changed-When: Mon Aug 27 12:34:10 2007
State-Changed-Why:
    What compiler did you use to build GDB?  Mark Mitchell has discovered that GCC 4.2.0 miscompiles GDB on Solaris SPARC; the bug is fixed in GCC 4.2.1.

 Hi,
 
 As you can see in the environment, I did use gcc 4.2.0
 When switching to 4.2.1, the bug was fixed.
 
 Thanks for the feedback,
 Arjan
