Bootstrap failure: element 1863 out of bounds in merge_blocks_nomove,at flow.c:2887

[Gerald Pfeifer]

Jan, RTH, I'm afraid you've been the last ones touching these parts of
the compiler?

We have a new bootstrap failure for a plain build on sparc-sun-solaris2.8:

stage1/xgcc -Bstage1/ -B/sw/test/gcc/SunOS/sparc-sun-solaris2.8/bin/ -c  -DIN_GCC    -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes   -DHAVE_CONFIG_H    -I. -Ijava -I/sw/test/gcc/cvs/gcc -I/sw/test/gcc/cvs/gcc/java -I/sw/test/gcc/cvs/gcc/config -I/sw/test/gcc/cvs/gcc/../include /sw/test/gcc/cvs/gcc/java/jcf-dump.c -o java/jcf-dump.o
/sw/test/gcc/cvs/gcc/java/jcf-dump.c: In function `main':
