Subject: refactor a RALLOC call that can tolerate failure to realloc
X-Git-Tag: 2.44.1~5^2~12

refactor a RALLOC call that can tolerate failure to realloc

We are about to make the RALLOC wrapper exit on allocation failure, so this
preserves the semantics of this call which handles allocation failure locally.
