[Bug ada/13442] New: Compiler crash in gnatlib bootstrap, SIGBUS at s-soflin.ads:145:4

[jan-jaap dot vanderheijden at phoenixbv dot com]

While building gnatlib in a manual bootstrap,
gmake CC="stage1/xgcc -Bstage1/" CFLAGS=-O0 GNATLIBCFLAGS=-O0 gnatlib

    [...]

../../xgcc -B../../ -c -O0      -W -Wall -gnatpg  a-caldel.adb -o a-caldel.o

Building stage1 works, the stage1 compiler can build gnatlib, gnatttools,
rebuild itself, but the stage2 compiler cannot build gnatlib (gnat 031217
miscompiles itself?).

Tried two ways: native bootstrap using gnat-3.14, and crossbuild with
crosscompiler from x86-linux.

$ stage1/xgcc -Bstage1/ -v
Reading specs from stage1/specs
Configured with: ../configure --prefix=/opt/gnu-031218 --enable-languages=c,ada
--enable-haifa --with-gnu-ld --with-gnu-as mips-sgi-irix6.5
Thread model: single
gcc version 3.4 20031217 (experimental)

Using binutils-031218, mips-sgi-irix6.5, irix-6.5.21m, IP30
