Happens when one tries to build gcc with -O3:

-W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes
-Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros
-Wno-overlength-strings -Wold-style-definition -Wc++-compat -DHAVE_CONFIG_H -I.

-I../../gcc/gcc/../libdecnumber/bid -I../libdecnumber ../../gcc/gcc/emit-rtl.c
-o emit-rtl.o
../../gcc/gcc/emit-rtl.c:5939:0: internal compiler error: in

Reduced testcase is attached.
