No. It is not accessible outside that function (or rather: accesssing it
is illegal). There is no concept of 'desolving' (whatever that may be).

Of course, when you use a C compiler it must implement what C requires.

Most HLL compilers (all?) will implement local variables in a
memory-efficient way, even on PICs that don't have a data stack (which
is the traditional way to implement re-use of local variables).

Note that this type of re-use is difficult to do in assembly, which is
IMHO one of the good reasons to use a HLL.
