Emulator Issues #704
closed
Crash loading plugins on Mac OS X
0%
Description
What steps will reproduce the problem?
- Run Dolphin.app
- Click on any of the plugin config buttons (i.e. audio)
- Dismiss the error stating that the .dylib cannot be found (despite it
existing in the path specified in the message) - The program will crash after the dialog is dismissed
What is the expected output? What do you see instead?
I expect to get the audio config dialog, but failing that, would expect the
system to not crash if it isn't finding it correctly.
What version of the product are you using? On what operating system?
SVN r2540
Please provide any additional information below.
This incident was reported in the forums. Here is the last forum post:
Interestingly, the program did not crash the first time I tried this in the
debugger. In my experience this means that there is a variable that was not
initialized to a default value, and depending on the compiler/OS, either
gets a sane default value or trash. However, it looks like m_DllConfig is
getting set to NULL in the CPlugin constructor, then set again using
m_hInstLib.Get. Maybe that .Get is returning garbage:
Download source Code
(gdb) print m_DllConfig
Cannot access memory at address 0x18
I do get an error message that pops up and then gets dismissed - that of
saying "Panic, can't open this dynlib plugin, it's missing" when in fact
the file is there, but I think the program state is corrupted much earlier
in execution, before the dialog.
Full backtrace:

Why r2540? You should get the latest svn (who knows, maybe it's fixed there?)
Anyway,
"Reason: KERN_PROTECTION_FAILURE at address: 0x00000018"
seems to say that your folder is protected/hidden? Try looking at that. Don't know
why
GetVideo()->Config((HWND)_Parent) worked when GetDSP()->Config((HWND)_Parent) didn't.

That's weird. I did this checkout earlier this week and that was the revision I got.
I just did an svn up, received r2565, and recompiled.
The problem persists with this revision. I checked the file permissions of
Dolphin.app/Contents/PlugIns/* - I have read and write access to all of these files
and directories. All of the directories have the execute permission as well, and I
checked to ensure that none of the files or directories had the OS X 'locked'
property set. I don't see how they'd be protected or hidden, unless there is some
implication given they exist inside an application bundle.
The graphics config does the same thing:
Program received signal EXC_BAD_ACCESS, Could not access memory.

How about finding a memory test program and running it? Perhaps some of your RAM is
bad?
Updated by fprimex over 15 years ago
Ran Rember (a front end to memtest http://www.kelleycomputing.net/rember/) and all
tests passed.

Well, it's got me stumped. I'm new though, so hrydgard can probably help you more.

just tried to compile r2599 but it doesn't work. Let me know if i need to post the errors

That might help, if they aren't identical to ones already posted.

I haven't tried to reproduce this yet, but just from looking at the backtrace:
0x00102939 in Common::CPlugin::Config (this=0x0, _hwnd=0x112ec80) at
Source/Core/Common/Src/Plugin.cpp:94
Doesn't the fact that this == NULL mean that the object hasn't been initialized? This doesn't give the root cause
of the problem, but we should add some error checking code. I'm going to venture to guess that the constructor
hasn't been called?

I had fixed this problem in my own custom build for OSX. but it wasn't a very good
way to do it. I'm looking in to why it does it now
Updated by Sonicadvance1 over 15 years ago
- Status changed from New to Fixed
Should be fixed in rev 3074. WX may still crash it sometimes.
