Jan,

We die in flow.c:init_propagate_block_info because even though the basic block
is a conditional jump, it seemingly has no successors.  Something is either
messing up or not building the RTL CFG properly.

Program received signal SIGSEGV, Segmentation fault.
init_propagate_block_info (bb=0x2000000002892a00, live=0x60000000000edac0,

There were a couple of changes from you that affected the CFG.  Could you take a
look?


Thanks.  Diego.

Hmm, i did no changes in this area, as you didn't approved my CFG
transparent expansion patch yet :)

I will look into it.  If you do have ia64 build, can you pass me
preprocessed source so I don't need to get binutils for the
crosscompiler?

It's all in the PR.  But Andreas found out that it was one of Zdenek's
patches that broke IA64.  So, you're off the hook :)
