Description Andre' 2010-07-08 16:51:30 UTC 
There seems no way to create a gdb.Type from a string "char[10]".

For non-arrays, gdb.lookup_type works:

   str(gdb.lookup_type('char')) == 'char'

but for arrays I get

   gdb.lookup_type('char[10]') 

   -> RuntimeError: No type named char[10].

Use the 'array' method on the constructed gdb.Type instance:

(gdb) py print(gdb.lookup_type('char').array(9))
char [10]

Yeah -- but I think what this bug is really about is having
a method like "gdb.parse_type" that will parse a type according
to the language rules.

Tom is right. 

It would be nice to have a roundtrip gdb.Type -> str(...) -> gdb.Type giving the original type as close as possible.
