Hi All,
I noticed a strange problem with gdb version 7.6 (our current RPM version)
Printing variables in in gdb is not possible.
I have the same problem on both gdb-7.5 and 7.6 (ubuntu 12.04 x64).
Some variables print OK, some get the 'can't compute CFA' error.
Gdb version 7.4 and earlier cannot read the symbol table at all, probably
due to unsupported dwarf version 4 produced by sparc-rtems4.11-gcc (gcc-4.8).
Most annoying ....
Jiri.

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
