Moving the code to hpux11, this is the error that causes the crash:

stage1/xgcc -Bstage1/ -B/opt/gnu/hppa2.0w-hp-hpux11.11/bin/ -c -DIN_GCC    -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long  -DHAVE_CONFIG_H    -I. -I. -I../../gcc/gcc -I../../gcc/gcc/. -I../../gcc/gcc/config -I../../gcc/gcc/../include ../../gcc/gcc/cfgbuil
d.c -o cfgbuild.o
