Do you mean that one?

I included the proposed patch in my gcc-4.6.1-mint-20110727, and I have no more trouble on ColdFire.
No, I mean the ones we've discussed on ACP forum some time ago, both are reported by me. I use your latest build chain.
Your provided zview.app does not start on FireBee/FireTOS because it is compiled with -m68020-60 and requires a 68881 compatible FPU, which is not emulated. However plain 68000 software compiled with GCC usually works very well (while slower than ColdFire optimized versions).
As soon as I make a proper build (probably with the older libraries for PDF), I'll compile also 68k version but it will be horribly slow (a lot of FPU stuff in freetype).
