The segfault occurs at line 1776 in alias.c:

      if (CONSTANT_P (y))

This generates a misaligned load.  The backtrace is as follows:

#0  memrefs_conflict_p (xsize=Variable "xsize" is not available.
) at ../../gcc/gcc/alias.c:1591
#1  0x40000000000b408c in true_dependence (mem=Variable "mem" is not available.
) at ../../gcc/gcc/alias.c:2142
#2  0x400000000021ccdc in loop_invariant_p (loop=Variable "loop" is not 
available.

#3  0x400000000022c1a8 in loop_optimize (f=Variable "f" is not available.

#5  0x4000000000305634 in rest_of_compilation (decl=Variable "decl" is not

Sorry, gdb isn't working very well on hppa64 at the moment.
