The memory allocated using request_mem_region should be released using
release_mem_region, not release_region.
The semantic patch that fixes part of this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression E1,E2,E3;
@@
request_mem_region(E1,E2,E3)
...
?- release_region(E1,E2)
+ release_mem_region(E1,E2)
