[Bug] MediaPortal crashing intermittently when interacting with the TV Guide (3 Viewers)

[RonD]

dumb question from a hardware chip design guy. The error seems to be a very strange stack overflow problem, does the MePo code do any type of setjmp/longjmp actions to jump out on N-level deep function calls to some top level code to return to a high level routine and skip doing a bunch of normal returns? Any way the return/restart stack state gets messed up?

When I googled "Exception code: 0xe053534f", a lot of the web links said this type of stack fault is a messy problem to debug/fix.

Hi,

No news and i really don't understand why on Titan skin, it try to focus and goes to a loop that lead stack overflow problem.
On SMP, it always goes back to ID 50.
In Titan when the pb occurs, it try all Image from Guide (so ID : 56000 55000 54000 and so and boom).
It surely a setting in skin but don't know where to look, so when do previous screen, it lead to crash. lol.

Hi Sebastii,

you still need further logs?

In StreamedMP the bug is ocassionally occurring still when I program recordings. (1 out of 20 maybe)
I observed that the crash occurs only when these 3 conditions are met
1) I programmed a recording (entry condition)
2) in TV Guide Main Overview I can not scroll over the EPG entries anymore. The cursor is fixed in the first colum of the syndicate names and the whole EPG field is scrolling (vertical scrolling still works there)
3) The cursor is suddenly disappearing completely in TV Guide Main Overview
When these 3 conditions are met any scrolling will cause a crash
When I leave the TV Guide before condition 3 is met, everything remains fine

Cheers,

Thanks
Yep for the logs in case it will show up something

I just reproduced the crash with Titan, but the MP logs stay empty:

Another crash to fix for 1.7 Pre...

2nd attempt does the same, throws another error:

No more news but i can reproduce the crash on 1.3.0 fresh install
I have installed fresh 1.3.0 -> scan one DVBS frequency -> Grab EPG (in france, i have just current/next) -> do the magic sequence -> Boom (crashed).
