[Bug c++/20505] New: internal error when compiling with -ggdb2 and no error with -ggdb1

[ivanr at syncad dot com]

When I try to compile with -ggdb2, it fails. When I try with -ggdb1, it doesn't.

version of GCC:
4.1.0 20050309 (experimental)

system type:
SunOS 5.8

GCC configure options:
./configure   --prefix=/usr/local/toolchain-4.0.0 --with-gnu-as --with-gnu-l
d --enable-languages=c,c++

command line:
g++ -v -save-temps -ggdb2 -c -o clockevent.41.o clockevent.41.ii

compiler output:
Using built-in specs.
Target: sparc-sun-solaris2.8
Configured with: ../gcc/configure --prefix=/usr/local/toolchain-4.0.0 --with-
gnu-as --with-gnu-ld --enable-languages=c,c++
