Xcode, no debug symbols for certain subclass

Question

I'm using Xcode 3.2.3 and iPhone SDK

So I'm trying to debug a UIView subclass, I hit a breakpoint in an overridden method and I can't see any symbols in either the GUI or gdb, just globals and registers.

This is what I see:

(gdb) po self
No symbol "self" in current context.

Yet when I set a breakpoint in a UIViewController subclass, all the symbols are there:

(gdb) po self
<MyViewController: 0x5c18ae0>
Current language:  auto; currently objective-c

Some things I've tried:

• clean all/rebuild
• restart Xcode
• change between debug and release
• config these options in Project settings:
  • GCC_DEBUGGING_SYMBOLS = All
  • Symbols DEBUG_INFORMATION_FORMAT = DWARF, DWARF w/ dSYM File
  • BUILD_VARIANTS = normal, debug
• threatening Xcode by swearing at it and typing rm -rf /Developer into a root bash prompt

Please help, my fingers are bleeding from debugging with NSLog

I experience this bug often. My workaround is typing the bt command on the gdb console, it then automagically sorts itself out and starts recognizing symbols in the current context.
