I have no problems running it on Fedora 26 with latest commit. I accidentally deleted my Ubuntu development VM, so when I'll set it up, I'll try it on Ubuntu. But I cannot see where the problem is.

Try it with 75b0af3 please, but I am not sure it will solve it, since the segfault on your end is bound to loading some WAV.

If this does not help, please add a debug log to the beginning of Engine/Resource/Loaders/WavResourceLoader::VGetLoadedResourceSize method to print the name of the resource for which it is failing, e.g.:

[Line 46]: LOG("Trying to load: " + handle->GetName());

and run it again and post the log here. Thanks.

Ok, i've found something, segfault appeared with sdl2 package upgrade from 2.0.5-4 to 2.0.6-1. Still works fine when i downgrade the package version.

Thanks for the update. I will try to reproduce it with that SDL2 version.

SDL2 guys must have broken something since I am not the only one with this problem:

Yeah I'm also using SDL 2.0.6 so this seems to be it.

@fragglet , great ! Let's hope they will issue some hotfix.

By the way, it works fine for me on Windows but it crashes on all linux distros.

Also on Windows when using the 2.0.6 version, the memory footprint of the game is almost 5 times greater than with 2.0.5 (with 2.0.5 it uses around 80-90 MBs of memory, with 2.0.6 it uses around 400 MBs) - this may be caused by wrong mixing specs described below after Mixer initialization, as all WAVs blow up in size 8 times.

Another thing is that when using 2.0.6 and doing:

Mix_OpenAudio(22050, MIX_DEFAULT_FORMAT, 1, 2048)

it disregards the options and instead the actual values after doing Mix_QuerySpec are:

Frequency - 48000
Format - 0x8120 (it does not fit any of the defined formats)
Channels - 2

This does not problem with 2.0.5 version.

When I update SDL version on windows, the game's memory footprint goes from 80MB to 400-500MB for some reason.

Not sure if this is same for linux as I dont have native linux machine, only one emulated in vmware (which does not store textures in GPU but rather in memory)

Hm, interesting, it looks like it utilizes memory far more than GPU on Linux.
At the start of the game:

+-----------------------------------------------------------------------------+
| Processes:                                                       GPU Memory |
|  GPU       PID   Type   Process name                             Usage      |
|=============================================================================|
|    0      1246      G   /usr/lib/Xorg                                277MiB |
|    0     17561      G   ./openclaw                                     3MiB |
+-----------------------------------------------------------------------------+

after 10th level was loaded (with SDL 2.0.4):

+-----------------------------------------------------------------------------+
| Processes:                                                       GPU Memory |
|  GPU       PID   Type   Process name                             Usage      |
|=============================================================================|
|    0      1246      G   /usr/lib/Xorg                                285MiB |
|    0     31762      G   ./openclaw                                    80MiB |
+-----------------------------------------------------------------------------+

I went to see also memory footprint when level was loaded and right before level was finished:

Level RAM at level start (MB) RAM at level end (MB)
1 301 325
2 378 394
3 502 -

Since playing the game until end of the level would take some time, i started to record RAM usage only after level was loaded:

Level SDL2 2.0.9 (MB) SDL2 2.0.4 (MB) SDL2 2.0.4 (MB, second time)
main menu 191 173 123
1 301 263 214
2 363 302 252
3 477 395 346
4 514 402 353
5 677 542 495
6 716 615 566
7 794 616 567
8 909 674 624
9 966 727 678
10 1000 745 696

If someone wants to test this also, this is what i used to get memory footprint:
ps -o rss= <process_id> | awk '{printf "%.0f\n", $1 / 1024}'

Yeah I have some major memory leaks scattered throughout the codebase... Mainly it's from bad approach to sprite/sound caching I think.

At some points I fixed some leaks, but rather high memory usage was never an issue so I didn't really focus on it specifically.

Hehe this isn't good... this is after loading levels 1 through 10.
