           Summary: Warning, when using switch-case expression
           Product: openSUSE 10.2
           Version: Final
          Platform: i686
        OS/Version: SuSE Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None

Hello,

when i compile a switch-case expression (found in the attachement), the
following warning is written:

/tmp/ccNQKs5H.s: Assembler messages:
/tmp/ccNQKs5H.s:21: Warning: expression dangerous with linker stubs
/tmp/ccNQKs5H.s:22: Warning: expression dangerous with linker stubs

Important is, that the optimization is enabled.
With optimization -O0, the warning is not written.
At all other optimizations, the warning is written.

This seems, that the compiler creates dangerous assembler code if optimization
is enabled.

If you need more information, let me know.
