attempts to start debugging (this works) and use the GDB dump command to dump the binary contents of a variable (GreyImage) to a file.

When using the examine (x) command to display the contents, it works fine

>x/10x GreyImage
0x4a7f8 : 0xbcc09bb6 0xb3a4bfb5 0xacaeb8bf 0xb7b6b3ae
0x4a808 <GreyImage+16>: 0xc2c1b1b8 0xb6b1c1c3 0xcabbbfbe 0xbccabeae
0x4a818 <GreyImage+32>: 0xc2c0b6b4 0xa3bec6bf

however, with either dump value GreyImage.dat GreyImage and also print GreyImage the result is

Info : dropped ‘gdb’ connection
Remote connection closed
Remote connection closed (from interpreter-exec console “print GreyImage”)

an immediate kill of the GDB session.
