Summary: Exim mis-uses db1.x API by assuming constant values
Product: Exim
Version: N/A
Platform: Other
OS/Version: Linux
Status: NEW
Severity: bug
Priority: medium
Component: General execution
AssignedTo: nigel [at] exim

Subject: Re: [exim] Exim with FreeBSD 8, dbm loop
Date: Thu, 30 Jul 2009 08:32:07 +0300
Message-ID: <9e20d71e0907292232u586f73l447c832e2a94a63 [at] mail>

dbstuff.h EXIM_DBSCAN definition for db 1.x uses a ->seq() flag value of 0 for
the next item; with FreeBSD 8, this breaks and leads to memory exhaustion.

Attached patch should be portable, unless someone knows of a conflicting
definition for R_NEXT on other platforms. Patch preserves existing behaviour
unless R_NEXT is defined.

This should probably go in for 4.70
