Did you compile in debug mode and make the symbol files available?

would the downvoter please leave a comment. Thanks.

Remove any non-ascii characters from both your your startup disk
and hostname (see the Sharing panel in System Preferences) and restart.

Ta da!

Did this work? Both my startup disk, and hostname are single words with only ASCII characters - but I don't see symbols either.

This helped me with 2.x style crash logs. For 3.0 style I had to learn some perl and fix the symbolicate script. There's probably a definite version by now.

What do you mean "fix the symbolicate script?" I'm stuck on this same issue without non-ascii characters in either place. Instruments *used* to work for me until my Snow Leopard "upgrade."

The script that adds symbols to your stack traces is called "symbolicatecrash". It's one of the least robust pieces of code I've ever seen. It uses spotlight to [fail to] find your .dSYM, ignoring the one in your app dir, the current dir, etc. It was incorrectly quoting shell chars when I fixed my version (this was after the non-ascii work around). If you're comfortable with perl you can debug it, or just google symbolicatecrash+snowleopard. Maybe someone's fixed it good.

I saw this happen, but on a different configuration. In Snow Leopard 10.6.1, Xcode 3.2, Instruments 2.0, I wasn't getting any symbols in Leaks when running iPhone OS 3.0 in the simulator. Searching in Apple's iPhone developer forums revealed that this was a known issue with the iPhone 3.0 SDK (that was being worked on), and switching the active SDK to 3.1 was a workaround. Sure enough, it worked for me!

I had the same issue and similarly switching the active SDK to iPhone 3.1 worked for me too. Thanks!

If your build target directory starts with "." (e.g. I was using ".xcode-build") then the .dsym files will not be found. For my case, changing the build directory to be "xcode-build" fixed the problem and now all my application's symbols show up in stack traces!

I had the same problem. It turned out I had set the build directory to /tmp/xcode. Changing this back to the default fixed the problem. This was with xcode 3.2.3.
