System: SunOS s2 5.8 Generic_108528-15 sun4u sparc SUNW,UltraAX-i2
Architecture: sun4
Sun Netra T1 200, 500MHz UltraSPARC IIe, 1GB, 2x18GB
Sun Solaris 7/01 MU 7
host: sparc-sun-solaris2.8
build: sparc-sun-solaris2.8
target: sparc-sun-solaris2.8
configured with: ../gcc-3.1-20020620/configure --enable-shared --with-gnu-as --with-gnu-ld --enable-threads --with-cpu=ultrasparc --enable-libgcj --with-system-zlib
>Description:
When gcc is configured with CFLAGS including "-g1", the bootstrap process fails with an internal compiler error when compiling the 64-bit (sparcv9 "-m64") version of eh_personality.cc in libstdc++/libsupc++.  The 32-bit version is compiled properly with -g1 without error.

>How-To-Repeat:
gcc -m64 -g1 -fno-implicit-templates -fdiagnostics-show-location=once -ffunction-sections -fdata-sections -c eh_personality.ii -fPIC -DPIC -o eh_personality.o

For complete bootstrap, on sparc-sun-solaris2.8:
env CC="gcc" CFLAGS="-O3 -g1" sh ../gcc-3.1-20020620/configure --enable-shared --with-gnu-as --with-gnu-ld --enable-threads --with-cpu=ultrasparc --enable-libgcj --with-system-zlib
make bootstrap
>Fix:
No fix.

Workaround: use -g0, -g2, or -g3.
