 I'm not the HPUX maintainer, so I'm not sure of the details.  There's a 
 reference to the 2.95.x problem here:
 
 	http://gcc.gnu.org/fom_serv/cache/59.html
 
 I believe most of the problems stem from the fact that the gcc-2.95 
 release series started before HPUX-11 was available; only relatively small 
 bug-fixes for supported OS variants ever get folded into 'dot' releases.
 
 As for your problems building gcc-3 on HPUX 11; I suggest you file a 
 separate PR on that problem.
 
 Richard.

State-Changed-Why:
    I've built arm-elf cross compilers successfully from a sparc host,
    so maybe the problem is your host environment (HPUX11, gcc-2.95.3).
    
    As far as I'm aware, gcc-2.95 isn't supported in this configuration,
    so I don't know how you are getting this even this far.
    
    Can you try building on a different host machine and let us know 
    if you still run into the same problem?

HPUX 11. gcc 2.95.3
>Description:
Gcc 3.0, with patch from PR 3147, configured for arm and multilib,
aborts with a ICE, when building the thumb libs.

With binutils onfigured as:
   ../binutils-2.11.2/configure --prefix=/opt/net/cygnus/arm-elf-gcc --target=arm-elf --nfp

and gcc-3.0 configured as:
   ../gcc-3.0/configure --prefix=/opt/net/cygnus/arm-elf-gcc --target=arm-elf --nfp --enable-multilib --with-gas --with-as=/opt/net/cygnus/arm-elf-gcc/bin/arm-elf-as --with-gnu-ld --with-ld=/opt/net/cygnus/arm-elf-gcc/bin/arm-elf-ld --enable-target-optspace --enable-languages=c,c++

Gives ICE on:

This is the output from that command:
