busy chrooted pdns_recursor crashed upon rec_control dump-cache

[zaphodb@…]

I issued a "rec_control dump-cache /var/tmp/pdns.cache" and after writing 60MB the recursor process was gone, rec_control hung, log only said:

Sep 26 13:55:23 cns1 pdns_recursor[17198]: STL Exception: basic_string::at

Nothing weird in the dump file, last line is

148.82.189.84.in-addr.arpa. 80262 IN PTR p54BD5294.dip.t-dialin.net.

the number of entries in the dump roughly amouts to max-cache-entries setting (1mio). Query load was about 600qps. I used c++ profiling for the build. Version is 3.1.3 patched with changeset 892.

Same here, using 3.1.4-snapshot.

Fixed in commit 900 (we hope)
