There are at least the following serious shared memory cache handling 
issues in the 2.0.54 code:

1) NULL payload pointers at full cache

2) wrong size of shm segment being used

3) mutex permissions not being initialized properly

(3) probably doesn't affect Win32 but the other two might.  I'm not 
aware of any apr_rmm bugs in the 2.0.54 (apr-0.9.6) code.
