big problem: signaled to death by 7

I think I have found something:

we are using flat file for quotas.db

the file quotas.db was 45056 bytes long --> crashing with signal 7
I noticed that 45056 was a multiple of  4096 and I begin testing around 
another clue was that the error message associate with mmap SIG BUS was 
that it happens when the application tries to read out of the buffer...
I found that imap is crashing if quotas.db is a multiple of 4096

the version of cyrus-imap I use is 2.3.1
if you need more details on the conf , you can ask me.

thank you very much

Best Regards
