When the index cache is disabled there is no issue loading the core dump. However when the index cache is enabled then the gdb process segfaults. For some reason this problem appears to be specific to the SUSE 12 platform.
Perhaps a clue will be how setting the index cache directory to a different location than its default of /home/ec2-user/.cache/gdb also avoids the segfault.
