rtl_fm and multimon-ng issues

Hi all, I've been using rtl_fm piped into multimon-ng for a while now which has been working pretty well for decoding POCSAG, I use this command line: rtl_fm -f 153.350M -r 22050 - | ./multimon-ng -t raw -a POCSAG512 -a POCSAG1200 -a POCSAG2400 -f alpha -D pocsag.db - I updated rtl_sdr today and now all I get is junk decodes POCSAG2400-: Address: 1318769 Function: 255 POCSAG2400-: Alpha: KA^MA POCSAG1200-: Address: 1700218 Function: 255 POCSAG1200-: Alpha: )"<DLE>'f POCSAG1200-: Address: 143961 Function: 255 I rolled back to an earlier version using git checkout commit and it appears the following commit broke it: c4fcfbb46e0a432902a2b78db4951bd20f68b9b2 Commit 8c3a99c8f7a88d7d2a05845d4b20cfcdacac4054 works fine, whereas the commit after causes multimon_ng to spit out garbage :-(
