request_mem_region should be used with release_mem_region, not request_region.
The semantic patch that fixes this problem is as follows:

// <smpl>

request_mem_region(start,...)
@b2@

request_region(start,...)
@depends on !b2@
expression r2.start;
expression E;

- release_region
+ release_mem_region
(start,E)
