It seems for me, that tvh tries to get epg data from an IPTV VOD file.
Removing the whole iptv network solves this issue temporarily.

- Status changed from Fixed to Accepted
Only the clang reported issue is fixed in v4.1-2371-g3654c98 (two different things are reported). Could you reproduce the second issue in clang ?
Updated by C K almost 9 years ago
Really? Looked the same for me :-)
Okay will recompile with clang
Updated by Jaroslav Kysela almost 9 years ago
The clang sanitizer does not report anything for this ? Also, provide log for '--trace epg,tbl-eit' (last 5000 lines prior the crash).
