crash when loading preview of cf player module #92

roberChen · 2021-12-12T18:41:04Z

I've encountered with this bug too many times. When I perform a text search on modules, it will likely to crash (I want to search filter and when I typed f it will crash ).
console output:

using Ardour6.9.0 (built using 6.9 and GCC version 11.1.0), and cardinal-git Version : r451.353594a-1

note that this bug has been existing at least several days, with many rebuilt to sync with newest version. Also, I was using pipewire-alsa but I think this is noting related to it.

The text was updated successfully, but these errors were encountered:

I fixed some conflicts that were happening today, so I think this is fixed now.
a full rebuild is needed.

worth trying with the standalone too, since you are building it yourself.
should be easier to get more info about it that way

so this bug seems to be related to cf, here is the related code:
https://github.com/CardinalModules/cf/blob/51506f16bb65104b5efb5294ace5ee912a9abcc9/src/PLAY.cpp#L252-L254

falkTX · 2021-12-28T17:42:55Z

a backtrace, that is very useful, thanks.

I dont get this crash on my side though, on all systems I have tried.
so maybe a compiler or system specific bug.

is this on archlinux?

roberChen · 2021-12-28T17:44:46Z

is this on archlinux?

yes, and specifically, manjaro linux, but build with SYSDEPS=false on this version.

roberChen · 2021-12-28T17:49:09Z

and the change I've made to get the backtrace:

you dont need to modify rack's makefiles, those are never used.

if you know a little bit of coding you could try to fix this and post a patch.
something like this should do it perhaps:

std::string fD = module ? module->fileDesc : "load sample";
std::string to_display = fD;
to_display.resize(14);

roberChen · 2021-12-30T08:46:11Z

@falkTX I've made a pull request to fix this bug, could you merge it?

falkTX · 2021-12-30T11:16:04Z

do you confirm the fix then?
we will need to send it upstream, not just in CardinalModules. but I can cherry-pick the commit(s)

roberChen · 2021-12-30T12:41:14Z

Didn't see any crash with this fix. And I also found this bug at three different modules.
