Log:
PR 78534 Regression on 32-bit targets

By switching from int to size_t in order to handle larger values,
r256322 introduced a bug that manifested itself on 32-bit
targets. Fixed by using the correct type to store the result of a
next_array_record call.

Regtested on x86_64-pc-linux-gnu and i686-pc-linux-gnu, committed to
trunk as obvious.
