We discussed this on irc a bit, but for the record, I think there are latent bugs that this patch will expose. For example, several tests in gdb.base use the same executable name: barimba. egrep 'set testfile.* "break"$' *.exp completion.exp:set testfile "break" condbreak.exp:set testfile "break" define.exp:set testfile "break" ena-dis-br.exp:set testfile "break" environ.exp:set testfile "break" info-proc.exp:set testfile "break" maint.exp:set testfile "break" Jan went through and fixed bugs like this for the current split.
