Subject: Fixed bug #948: SRU Request reliably coredumps metaproxy (possibly high
X-Git-Tag: METAPROXY.1.0.10~24
X-Git-Url: http://git.indexdata.com/?a=commitdiff_plain;h=873ade0594902585596f39645598427d9e961e9a;p=metaproxy-moved-to-github.git

Fixed bug #948: SRU Request reliably coredumps metaproxy (possibly high
value for maximumRecords). Problem was due to result sets being
truncated and that exposed an array bound violation in the multi filter.
