Problem occurs in call_init trying to run constructors for newly built
libc.so.6.

/home2/dave/debian/glibc/eglibc-2.11.2/build-tree/hppa-libc/libc.so.6:
+file 
format elf32-hppa-linux

Contents of section .init_array:
159008 ffffffff 0015bee2 00000000           ............    

The ffffffff and 00000000 appear to come from merging .ctors into .init_array.
Calling 0xffffffff causes the segv.  ffffffff and 00000000 mark the limits
of .ctors as generated by crtstuff.c.

Building binutils with --disable-initfini-array avoids the error.

Not much documentation on this...
