Summary: check_snmp memory corruption with many OIDs/labels/units

Initial Comment:
I'm trying to read five OIDs with units and labels with check_snmp v1.4.15 (from current EPEL6 RPMs), and getting misformatted output. (Four OIDs work fine.)


Sample output (from an APC NetBotz):

[root at netman plugins]# ./check_snmp -H bh-ctc-nbotz -C public  -o .1.3.6.1.4.1.5528.100.4.1.1.1.2.2641473744 -l 'temp0' -u 'Cx10'  -o .1.3.6.1.4.1.5528.100.4.1.2.1.2.509758980 -l 'humid0' -u '%x10'  -o .1.3.6.1.4.1.5528.100.4.1.3.1.2.3358498259 -l 'dewpoint0' -u 'Cx10'  -o .1.3.6.1.4.1.5528.100.4.2.3.1.3.1571793337 -l 'motion' -u ''  -o .1.3.6.1.4.1.5528.100.4.1.5.1.2.3240202735 -l 'airflow' -u 'm/minx10'

\è OK - temp0 223 airflow humid0 450 %x10 dewpoint0 97 Cx10 motion 0  airflow 305 m/minx10 | temp0=223 humid0=450 dewpoint0=97 motion=0 airflow=305

(Note: Initial "SNMP" text was corrupted, and first units shows "airflow" instead of "Cx10".)


[root at netman plugins]# ./check_snmp -H bh-ctc-nbotz -C public  -o .1.3.6.1.4.1.5528.100.4.1.1.1.2.2641473744 -l 'temp0' -o .1.3.6.1.4.1.5528.100.4.1.2.1.2.509758980 -l 'humid0' -o .1.3.6.1.4.1.5528.100.4.1.3.1.2.3358498259 -l 'dewpoint0' -o .1.3.6.1.4.1.5528.100.4.2.3.1.3.1571793337 -l 'motion' -o .1.3.6.1.4.1.5528.100.4.1.5.1.2.3240202735 -l 'airflow'

SNMP OK - temp0 220 humid0 450 dewpoint0 95 motion 0 airflow 305 | temp0=220 humid0=450 dewpoint0=95 motion=0 airflow=305

(Note: No units, all looks OK.)


[root at netman plugins]# ./check_snmp -H bh-ctc-nbotz -C public  -o .1.3.6.1.4.1.5528.100.4.1.1.1.2.2641473744 -l 'temp0' -o .1.3.6.1.4.1.5528.100.4.1.2.1.2.509758980 -l 'humid0' -o .1.3.6.1.4.1.5528.100.4.1.3.1.2.3358498259 -l 'dewpoint0' -o .1.3.6.1.4.1.5528.100.4.2.3.1.3.1571793337 -l 'motion' -o .1.3.6.1.4.1.5528.100.4.1.5.1.2.3240202735 -l 'airflow' -u 'Cx10,%x10,Cx10,,m/minx10'

SNMP OK - temp0 217 Cx10 humid0 420 %x10 dewpoint0 82 Cx10 motion 0  Cx10 305 | temp0=217 humid0=420 dewpoint0=82 motion=0 Cx10=305

(Note: Units gathered together, label for "airflow" gets changed to "Cx10".)


[root at netman plugins]# ./check_snmp -H bh-ctc-nbotz -C public  -o .1.3.6.1.4.1.5528.100.4.1.1.1.2.2641473744 -o .1.3.6.1.4.1.5528.100.4.1.2.1.2.509758980 -o .1.3.6.1.4.1.5528.100.4.1.3.1.2.3358498259 -o .1.3.6.1.4.1.5528.100.4.2.3.1.3.1571793337 -o .1.3.6.1.4.1.5528.100.4.1.5.1.2.3240202735 -l 'temp0,humid0,dewpoint0,motion,airflow' -u 'Cx10,%x10,Cx10,,m/minx10'

SNMP OK - Cx10 213 Cx10 420 %x10 78 Cx10 0  305 | Cx10=213 iso.3.6.1.4.1.5528.100.4.1.2.1.2.509758980=420 iso.3.6.1.4.1.5528.100.4.1.3.1.2.3358498259=78 iso.3.6.1.4.1.5528.100.4.2.3.1.3.1571793337=0 iso.3.6.1.4.1.5528.100.4.1.5.1.2.3240202735=305

(Note: Gathered labels and units together, now OIDs show up in odd places.)
