I've compiled and run a large program under the address sanitizer.  I have
two code paths involving asprintf or vasprintf wherein asan detects a fault
when the value returned from asprintf/vasprintf is freed.  In one case,
asan complains about a double-free; in another case asan complains about an
illegal free.

My attempts to reproduce this with a small test case have failed.

Before I spend more time on reproducing this, I was wondering if
asprintf/vasprintf were known to be problematic?
