output formats bug?

output formats bug?

[Chris Zankel]

GDB seems to be stuck with the constant char output format
once that was used:

(gdb) x/c main
0x804830c <main>:       85 'U'
(gdb) x/w main
0x804830c <main>:       85 'U'
(gdb)

(This is not a new bug, it seems to be there for a long time)

The thing is, w isn't an output specifier - it's a size qualifier.  It
changes the size qualifier to "word".  Then the code for printing a
char ignores it.

The behavior you want is probably:
x/c main
x/x main
