Problems printing variables in sparc-rtems4.11-gdb 7.6

[Ralf Kirchner]

Hi All,
I noticed a strange problem with gdb version 7.6 (our current RPM version)
Printing variables in in gdb is not possible.

Scenario:
rk at linux-aiv4:~/git-rtems-testing/rtems/build-sparc-sis-rtems/sparc-rtems4.11/c/sis/testsuites/fstests/fsdosfsname01
> sparc-rtems4.11-gdb *.exe

Has anybody else seen such problems with gdb 7.6?
Am I doing anything wrong? Does version 7.6 need any special treatment
to work correctly?

Kind Regards
