As well, the following bootstrap failure on the 3.3 branch occurred on hppa-unknown-linux-gnu: stage1/xgcc -Bstage1/ -B/home/dave/opt/gnu/gcc/gcc-3.3-sjlj/hppa-linux/bin/ -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long -DHAVE_CONFIG_H -DGENERATOR_FILE -o genrecog \ genrecog.o rtl.o read-rtl.o bitmap.o ggc-none.o gensupport.o insn-conditions.o print-rtl1.o \ errors.o ../libiberty/libiberty.a ./genrecog ../../gcc/gcc/config/pa/pa.md > tmp-recog.c make[2]: *** [s-recog] Error 137 I had to kill genrecog as it was hung in a loop. I haven't specifically identified your patch as causing the genrecog problem but it was installed in the period between the last successful bootstrap and the above failure. Dave -- J.
