[Pkg-net-snmp-devel] Bug#418012: libsnmp9: Too noisy when parsing counter64 on x64 system

[Bin Tian]

Package: libsnmp9
Version: 5.2.3-7
Severity: normal

On AMD64 system, when parsing a counter64 variable, it will output
something like that:

truncating unsigned value to 32 bits (6)
truncating unsigned value to 32 bits (6)
truncating unsigned value to 32 bits (6)
truncating unsigned value to 32 bits (6)
truncating unsigned value to 32 bits (6)
truncating unsigned value to 32 bits (6)

On 32bit systems you couldn't see these messages. And these messages 
should be suppressed.
