Your build settings below look reasonable, but given where the crash
is happening it looks like the problem is with your main nib file. Is
it possible that it contains a new Leopard-only view class, for
example? Does IB show any incompatibilities with your xib or nib with
a 10.4 target?
And I'd suggest getting your hands on a 10.4 system of your own,
particularly if current or future customers have that as a
requirement. My customer does so I'm doing all my development with
Xcode 2.5 on a 10.4.11 system. I make sure everything works on 10.4
first, then also make sure that nothing weird happens on 10.5.

I'm in a sticky situation. I personally have no machine capable

tiger, but they are reporting that it is failing.
What's going wrong:
The application crashes almost immediately (on tiger, but not
leopard) while loading its nib, here's the back trace:

What I've done to try and get it to run on tiger:
Set the following build settings in my target:
ARCHS = $(ARCHS_STANDARD_32_BIT)
SDKROOT = macosx10.4
MACOSX_DEPLOYMENT_TARGET = 10.4
GCC_ENABLE_OBJC_GC = unsupported
In the xib file, set the target to 10.4 (I've also tried saving a
version 2.0 nib instead of a xib).
I'm building using Xcode 3.1.2.
If anyone could point me to what setting I've missed, or some
documentation I can read on this, I'd be really grateful.
