I erased every trace of experimental GCC versions and support libraries. Then I

I built GCC using libunwind and binutils 2.19.1 and there is the same problem.
The registers are *not* being restored to the right values after the exception
return.
In the following assembly code you can clearly see

I will work on trying it with libunwind and then with binutils 2.19. Those seem

The actual segfault seems to happen in the .plt section. I am not entirely
clear on how this is laid out and how to find what symbol is where.
But on entry to the plt code, the r1 register is set to an invalid memory

I agree. This would be very useful. I am trying to do this very thing and am

Do you mean that it may not be valid to take the address of a global struct
with partial definition? For example in udns_init.c which does not define
dns_defctx, but has

Forgot to mention, I filed a bug for fwrite too:

Until they fix that (if they do) it will be useless to check fwrite's return
