Are you sure that the code was actually using the ucontext interface?  
USE_UCONTEXT doesn't seem to be defined in the PPC linux param header 
files, so my guess is that you were using the setjmp based code and 
getting bit by the glibc stack pointer mangling.  If that's the case, a 
possible simple fix would be to define USE_UCONTEXT in 
src/config/param.ppc_linux2x.h - as was done for i386 to tackle the same 
problem.
