When I briefly ran vdr under valgrind earlier this month, it threw up
a number of potential memory leaks in eepg, so I'm surprised you're
not seeing those. I'll have a quick look on my box later to see if I
have the .log output handy.
EEPG also caused a segfault in VDR a few times whilst valgrind was
running. Tbh it should probably be rewritten from scratch, ideally
with separate plugins for each of the supported extended epg services,
so you can run a minimal set.
