It looks like that the *desc RB tree structures are malformed for a reason. But I don't see why in the code. Could you run clang or valgrind memory checker? https://tvheadend.org/projects/tvheadend/wiki/Debugging#Memory-leaks-or-corruption

Updated by Bastian Kleinschmidt about 6 years ago

Shure i will do.
Ps : i see a memory leak in 4.3~1249 after 20+ days running (8gb or more).

Updated by Bastian Kleinschmidt about 6 years ago

hi, its crazy, but the error went away after i recompile the current git with additional "-disable-pie --enable-ccdebug python=python3 cc=clang ld=clang nowerror" for debugging.

i will have a look on it.

#4

Updated by Bastian Kleinschmidt about 6 years ago

Maybe a bug in gcc ? I use gcc 4.8.5
Tomorrow i will build again with gcc and use valgrind.

#5

Updated by Bastian Kleinschmidt about 6 years ago

ok, i finished debugging.
logs attached .

what i know :
build with ccache, clang = no crash

build with gcc = crash
build with gcc and use valgrind = no crash

The valgrind output helped. I hope it's definitely fixed now.

If you use verion (4.1-4156~g7b42e43) is too old normal to crash, install last one 4.3-1317~g4f3bb16fa and try again.
