Segmentation fault with the Simulator under VMware

[dip]

I created the simulator for iPod Video with 64MB using the latest svn sources using the VMware images from the wiki. It compiles without problems but when I run the simulator and try to play a song I get a the message "Segmentation fault (SDL Parachute Deployed)". It happens both when I browse the filetree as well when I use the database.

Any ideas what could be wrong?

I forgot to mention that a normal build works without problems on my iPod 5.5 80GB, only the simulator crashes.

It sounds like a bug. Start debugging it or check if there's an existing bug report filed for it and if it isn't provide lots of info on how to repeat it in a new one.

I tested it in cygwin and there the simulator works fine. So the problem only arises when I use VMware to compile the simulator. Before filing a bug report I just want to be sure that it is not a problem of my VMware installation. So if anyone can confirm the bug when using VMware this would be good.

The crash simply occurs when you select a song to play either through the filetree or through the database. The above error message is shown on the console window and the simulator gui is frozen.

Does it matter what codec the song is encoded with, or does it happen with any file format ?

I definitely tested it with ogg vorbis files and I guess also with mp3 files (I'm not completely sure since it's some days ago when I first tested it and today I only repeated the test with ogg files). At the moment I am at work but I will try it this night with different file types and report again.

Why don't you run it with gdb and post the debug log?

Since I don't know that . What do I have todo for that?

I presume you are on Windows. gdb (the GNU debugger) comes with Cygwin. Here is a quick tutorial:

from the Cygwin manual.

Yes I am using Windows XP but as mentioned above, the cygwin version runs without problems. Only the VMware version (Debian Linux) of the simulator crashes. So I must run the debugger in VMware. Are there special instructions for that also?

The debugger runs the same. However, here is a more detailed tutorial:

Running the debugger and going straight ahead to the music directory to play an ogg vorbis file resulted in the following messages:

When choosing an mp3 file the same crash happens.

When choosing a wma file it does not crash. However, the WPS is shown but the song is not playing, it remains at 0:00.

I downloaded now a completely new version of the vmware image to another Windows XP computer and installed vmplayer the first time on this computer. Then I checked out the current daily version of rockbox and compiled it for the simulator (iPod Video, 64MB).

I started the simulator did not change any settings, did not build the database and tried to play an audio file through the file browser. I got immediately the same segmentation fault so it should be clear that this is not related to my system.
