Very simple sf::Music test crashes
« on: January 04, 2015, 09:00:22 pm »
On OS X 10.10, with both SFML 2.2 and Git head, running the following piece of code causes a Bus error:
int main()
{
        sf::Music music;

        if (! music.openFromFile("test.wav"))
                return 1;

        return 0;
}

The file "test.wav" does not exists, so failure is ok but it should not crash. LLDB backtrace is as follow:
Code: [Select]
* thread #1: tid = 0x1096d8, 0x00007fff951b3fcf libsystem_platform.dylib`OSSpinLockLock + 7, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=2, address=0x100000f74)

I guess does also happen on the no libsndfile branch but could you test it?

Dunno if the location change is relevant though.

I checked on 10.9, no problem to report.

Could you paste the stack of all threads?

In case you are using gdb and don't know how to do that, it's "thread apply all backtrace".

Will the crash always happen if you have an sf::Music object or can you add some code and it doesn't happen anymore?
Do you get similar issues with sf::Sound?

I couldn't find anything helpful in those other threads bt.. In three of them it crashes in OSSpinLockLock and one of them in _OSSpinLockLockSlow (which is not documented...). In all cases, it entered pthread_mutex_destroy which should return an error code on failure (EBUSY/EINVAL), not crash... And I couldn't find anything really similar on the Web.. :-\

Does it also happen with 2.1? (need to apply https://github.com/SFML/SFML/pull/699.patch or similar)

Actually I was wondering why I was having the crash when compiling the sample manually, but not within Xcode. And I found out that any optimization level other than -O0 makes the crash disappear…

I also noted that the "Current" link in the SFML audio framework links to version 2.1 of the binary, not 2.2, although I just installed SFML thought the "install" target.

Edit: fixing the symbolic link allowed the debugger to show the relevant line of code in SFML sources rather than assembly lines.

Edit 2: by the way, why does the install target installs both version 2.1 and 2.2 of the binaries? Actually it says it's already up-to-date but I don't understand why it even cares about the old version:
Code: [Select]
-- Installing: /Library/Frameworks/sfml-audio.framework
-- Up-to-date: /Library/Frameworks/sfml-audio.framework/Resources
-- Up-to-date: /Library/Frameworks/sfml-audio.framework/sfml-audio
-- Installing: /Library/Frameworks/sfml-audio.framework/Versions
-- Installing: /Library/Frameworks/sfml-audio.framework/Versions/2.1.0
-- Installing: /Library/Frameworks/sfml-audio.framework/Versions/2.1.0/Resources
-- Up-to-date: /Library/Frameworks/sfml-audio.framework/Versions/2.1.0/Resources/Info.plist
-- Up-to-date: /Library/Frameworks/sfml-audio.framework/Versions/2.1.0/sfml-audio
-- Installing: /Library/Frameworks/sfml-audio.framework/Versions/2.2.0
-- Installing: /Library/Frameworks/sfml-audio.framework/Versions/2.2.0/Resources
-- Up-to-date: /Library/Frameworks/sfml-audio.framework/Versions/2.2.0/Resources/Info.plist
-- Up-to-date: /Library/Frameworks/sfml-audio.framework/Versions/2.2.0/sfml-audio
-- Up-to-date: /Library/Frameworks/sfml-audio.framework/Versions/Current
Edit 3: removing the old binaries from the SFML build directory allowed me to install only the relevant stuff with the correct binaries :)

Ok I feel stupid now ;D the culprit was my old SFML headers in /usr/local/include, which were used instead of the ones in the SFML framework. Now it runs fine whatever I do ::)

:D

Be careful though with the fact that it looks to be installing whatever binary it finds, even if it's old SFML ones, and especially the fact that the "Current" link does not target the freshly installed version.
