fast click crash while previewing sound presets.

[netpipe]

if you click too fast while previewing sound preset xpm a crash occurs. a possible workaround could be to add a minimum play time to the previewing of xpm's

[musikBear]

sound preset xpm

could you be more specific 'xpm' is that presets for a vst?
I do not have any *.xpm file in default lmms at all?

[netpipe]

xpf sorry https://lmms.io/lsp/?action=show&file=4211 here is a good example , happens more on complex sounds or when the system is thinking hard

[zonkmachine]

I can confirm this on commit 979fa2f
@curlymorphic Your the go-to guy on everything that happens to the left, right? :D

QtXmlWrapper::loadXMLfile(): empty data
Segmentation fault (core dumped)

It either hangs or crashes with the above Qt comment.

[musikBear]

also confirmed on 1.1.3 win32
I have to click like insane, but then it does hang

[Wallacoloo]

I seem to be getting a different error every time I try this on master w/ 64 bit Ubuntu 15.04. Half of the time it's a segfault in ~Engine() (see #2049), other times it's a segfault in another part of ZynAddSubFX, and sometimes it even hangs somewhere when trying to acquire a lock on something.

Here's one stacktrace for a segfault that occasionally occurs on the very first press (regardless of if I hold the mouse or just tap it):

Program received signal SIGSEGV, Segmentation fault.

Here's one where it hangs instead of crashing. This seems to reliably happen if I can tap Fusion Bell I.xpf and get it to keep playing after I release it, and then click it again:

I'm gonna fiddle around with Valgrind and see if it reveals anything trivial for the first case.

[Wallacoloo]

Here's the Valgrind log that I get when I click the .xpf file for the first time (it plays ok and does not crash - but that's probably just thanks to Valgrind): https://gist.github.com/Wallacoloo/f28e905edea6cb0102b1

All of the errors Valgrind catches point to essentially the same piece of code. Let's take this one:

==15808== Invalid write of size 4
==15808==    at 0x8373870: std::string::_M_mutate(unsigned long, unsigned long, unsigned long) (in /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.20)

[...]

If you'll notice, it looks like we're experiencing a similar name-conflict error in which Zyn's NulEngine constructor is calling the wrong Engine base class (LMMS' Engine instead of Zyn's own Engine).

Indeed, gdb confirms this is the case:

$ gdb ./lmms
(gdb) b Engine.h:45

Also, the offending line is this one, in NulEngine::NulEngine():

name = "NULL";

Notably, name is a std::string field that NulEngine inherits from Engine. It is quite possible then that because the wrong Engine constructor is being called, std::string is never being initialized and so the assignment operator tries to do something illegal.

There could still be more at play than this classname conflict, but it potentially explains all the segfaults I saw - we definitely need to figure out the whole Engine name conflict.

@Wallacoloo nice research

As far as the engine name clash goes. In the ZSAF 2.5 upgrade, I moved the engine class to the Zyn namespace during my tidying up of the pull request over the weekend.

@Umcaruje -where are we with this ?
Your Master (1.1.3.1.7.15) crashes almost emediately if pre-veiw in 'MyPresets' is attempted, but this pre-view ticket is also still open, so i guess this is already known about Master (?)

[Umcaruje]

@musikBear this issue will be solved by either #1991 or #2064 or #2118. I can't quite understand your question though. If an issue is fixed, it will be closed. If its not fixed its open. This issue is open, which means its not fixed.
