BUG/MINOR: sample: exit regsub() in case of trash allocation error

Browse source 
As reported in issue #507, since commiy 07e1e3c93e ("MINOR: sample:
regsub now supports backreferences") we must not proceed in regsub()
if we fali to allocate a trash (which in practice never happens). No
backport needed.
