powerpc-unknown-linux-gnu bootstrap failure


Howdy,

The trunk fails to bootstrap on my powerpc-unknown-linux-gnu
system:

 stage1/xgcc -Bstage1/ -B/usr/local/powerpc-unknown-linux-gnu/bin/ -c   -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long -fno-common -Werror   -DHAVE_CONFIG_H -DGENERATOR_FILE    -I. -I. -I../../gcc/gcc -I../../gcc/gcc/. -I../../gcc/gcc/config -I../../gcc/gcc/../include ../../gcc/gcc/gensupport.c -o gensupport.o
 ../../gcc/gcc/gensupport.c: In function `shift_output_template':
 ../../gcc/gcc/gensupport.c:706: internal compiler error: Segmentation fault
 Please submit a full bug report,
 with preprocessed source if appropriate.
 See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
 make[3]: *** [gensupport.o] Error 1

It faults on the first line of remove_all_occurrences when it
dereferences forest_node, which is NULL.  The backtrace reaches
back to the call to delete_from_dominance_info in find_if_case_1.
The dominance info is NULL because the block was created on a
previous if_convert pass, after calculate_dominance_info.

How is the dominance info for this block supposed to be created?

Matt
