Good to know.

Yes, it _is_ armv5te (xscale). You meant v4, I guess.
The real problem was a floating point issue, with mis-matched ABI: compiler
was built with soft-float (VFP? FPA?) support, while C library was built with
hard-float VFP support. Symptom was that setjmp(3) was not wotrking. Took me
10 days to figure out... Sigh...

Yann E. MORIN.
PS. I'm rolling-out a bug-fix release of crosstool-NG tonight for those
interested.
YEM.
