What about

A handler for the OS ABI "GNU/Linux" is not built into this configuration
of GDB. Attempting to continue with the default i386:x86-64:intel settings.
Selected architecture i386:x86-64:intel is not compatible with reported target architecture i386

that happens to me as well and it results in crashes when I try tu debug...
