Tvheadend

I think I've found the culprit. I found the dvr log file shown below. Note under files>info>duration>4294967290

This value is large enough for an uint but obviously not int. If I change this value to max(int) -1, tvheadend no longer crashes on a kodi client connection. I'm not aware of how the value '4294967290' was determined. I noticed that in service.h, elementary_stream_t, es_frame_duration is defined as int. I haven't located where in the source the dvr log files are written or read yet.

Could you provide trace using tvh binary with the debugging symbols ?

When I do the back trace I just get this (gdb --args ~/src/tvheadend/build.linux/tvheadend -c ~/test-conf -d):

#0 0x76b8b8dc in raise () from /lib/arm-linux-gnueabihf/libc.so.6

#3 0x0000b624 in ?? ()

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

Am I doing something wrong?

I managed to get this trace from gdb:

Fine. Could you put breakpoint to fcn htsmsg_binary_write() , line 220 - abort() call and inspect structure *f ?

Breakpoint 1, htsmsg_binary_write (msg=<optimized out>,
