No, nice catch! The manual states:
> Local variables of type value must be declared with one of the CAMLlocal macros. [...] These macros must be used at the beginning of the function, not in a nested block.
Note that there are a number of existing instances of `CAMLlocal` in nested blocks in this file. Shall I change them at the same time?
