 I have retried with 3.2.3 and I still get the same result.

 Contrary to my original guess in this PR, I now believe that configuring using '--with-dwarf2' *is* required to provoke the problem.
 
 Here's my configure command:
 
   ../src-hpux_11-hppa2_0w/configure \
           --prefix=/home/sdouglas/tools/GNU/gcc/3_2_3 \
           --exec-prefix=/home/sdouglas/tools/GNU/gcc/3_2_3/hpux_11-hppa2_0w \
           --program-suffix=-3_2_3 \
           -v --with-dwarf2 --enable-version-specific-runtime-libs --with-gnu-as --with-as=/home/sdouglas/tools/GNU/binutils/2_13_2_1/hpux_11-hppa2_0w/bin/as-2_13_2_1
 
 Here's my make command:
 
   make STAGE1_CFLAGS=-O2 BOOT_CFLAGS=-O2 MAKE=make bootstrap-lean
 
 I can supply pre-processed source -- but the problem may well require that the xgcc has been built with --with-dwarf2.  Let me know if you'd like pre-processed source and where to send it to.
