Description
config looks like this:

I can enable gsmtap for various other SAPI without any crash, but as soon as I enable gsmtap-sapi for pdtch, osmo-bts-trx crashes:
OsmoBTS(config)# bts 0 OsmoBTS(bts)# gsmtap-sapi enable-all Enable all kinds of messages (all SAPI) disable-all Disable all kinds of messages (all SAPI) bcch BCCH ccch CCCH rach RACH agch AGCH pch PCH sdcch SDCCH tch/f TCH/F tch/h TCH/H pacch PACCH pdtch PDTCH ptcch PTCCH cbch CBCH sacch SACCH OsmoBTS(bts)# gsmtap-sapi bcch OsmoBTS(bts)# OsmoBTS(bts)# gsmtap-sapi ptcch OsmoBTS(bts)# OsmoBTS(bts)# gsmtap-sapi pacch OsmoBTS(bts)# OsmoBTS(bts)# gsmtap-sapi pdtch OsmoBTS(bts)# OsmoBTS(bts)# Connection closed by foreign host
This is of course not particularly helpful when wanting to debug GPRS issues...
