A mere pointer assignment? There is not much possible semantics there
to worry about. Yes, it'd be illegal to dereference the char* pointer.
It may be legal to cast it back to "int (*) ()" and call through that,
if "char*" is as big as "int (*) ()".
Some of this discussion seems to me to focus too much on how
fundamentally nonsensical operations may be expressed in nonsensical
gdb expression syntax.
