This is probably PR tree-optimization/21030. Ada bootstraps on
i386-pc-solaris2.10 and mips-sgi-irix5.3 fail in stage 2 with the same
error:
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 |
The patch proposed in the PR doesn't fix this.
