[Bug tree-optimization/21030] [4.1 Regression] ICE in set_value_range building 176.gcc with -O2


------- Additional Comments From ro at gcc dot gnu dot org  2005-04-20 16:42 -------
I observe the same ICE when bootstrapping with Ada on i386-pc-solaris2.10:

stage1/xgcc -Bstage1/ -B/vol/gcc/share/i386-pc-solaris2.10/bin/ -c -g -O2     
-gnatpg -gnata -I- -I. -Iada -I/vol/gnu/src/gcc/gcc-dist/gcc/ada
/vol/gnu/src/gcc/gcc-dist/gcc/ada/sem_intr.adb -o ada/sem_intr.o
+===========================GNAT BUG DETECTED==============================+
| 4.1.0 20050419 (experimental) (i386-pc-solaris2.10) GCC error:           |
| in set_value_range, at tree-vrp.c:124                                    |
| Error detected at sem_intr.adb:437:1                                     |

Unfortunately, the proposed patch doesn't fix this.
