To debug the problem, I would suggest turning on the DYLD_PRINT_LIBRARIES environment variable and see if it stops printing at a certain library, then check to make sure that library is both 64 bit and GC capable.
However, for best performance on 10.5.x, I would suggest compiling your launcher app as a 32/64 bit application. 32 bit applications on 10.5.x will be more efficient in that the 32 bit chunks of all the shared frameworks are always "kept hot" by other applications -- you'll tend to page less under memory pressure with a 32 bit app on 10.5.x. (The opposite is true on Snow Leopard and, as more and more applications go 64 bit, it'll become more-so over time).
