Yes it is in line 67. Maybe I will have

Yes, the test cases that failed with the last snapshot are:

Maybe I will have some time to look at the other test cases next week.

I did only try the trunk,
I'd expect the build-configuration (using hard float)
to influence the ABI.
This will likely not happen on a ARMv5, without FPU registers.
