data formatters unreliable?

I've been trying to use some custom summary formats and data formatters to make my debugging experience a bit saner. Potentially, this is a very handy feature of XCode, but instead it seems to be driving me further towards the edge!

I have a formatter plugin based on the wchardataformatter sample code. When I test this plugin using the small test program provided, it works fine.

When I test it in my own code (spread over 3 projects incidentally - an application linked to two static libraries), and look at wchar_t* strings, it _sometimes_ works, and sometimes doesn't - with no obvious explanation as to why.

When I test it in my own code using custom types derived from wchar_t and wchar_t*, I can't get it to work at all, although I did tantalisingly get it to work once!

Are there any known issues with this stuff? Does it work reliably for everyone else? Are there any project settings that need to be given certain values - e.g. using DWARF instead of Stabs, or turning Fix & Continue off, or something similarly obscure.

I occasionally get "warning: Attempt to use a type name as an expression." appearing in the gdb debug console.

I'm using XCode 2.4 on intel macs (a MacBookPro and a MacPro) using 10.4.8.

Yours in frustration...
