Since it appears that you can reproduce this problem, it ought to be easy to 
identify the cause using valgrind.

Meanwhile, 2.4.40 is 3 releases behind and we're about to release 2.4.44. If 
you can reproduce the problem in the current RE24 release candidate and track 
it down in valgrind there may be time to fix it for the 2.4.44 release. 
Otherwise, you'll have to wait for the next release.
