I have found an ICE

[Magnus Fromreide]

I have configured the compiler as follows:

../gcc/configure --prefix=/usr/local/src/gnu/gcc-2.97/install
--enable-languages=c,c++ --enable-version-specific-runtime-libs
--disable-nls

and have found the following oddities:

make check results in

...
./mkcheck 0 `pwd` ../../../gcc/libstdc++-v3
running mkcheck
./mkcheck: testing the build directory
You need bash 2.x to run mkcheck.  Exiting.

How do I specify the path to bash 2.x? I do have one installed.

Compiling the attached file results in the following errors:

Please submit a full bug report.
 See <URL: http://www.gnu.org/software/gcc/bugs.html > for instructions.

The compiler do install bits/c++config.h as
/usr/local/src/gnu/gcc-2.97/install/i586-pc-linux-gnu/include/g++/bits/c++config.h
but for some reason is that not on the search path.

The internal error seems to originate in the method body being optimized
away from the tree, why this happens is currently beyond me. With -O2 it
compiles.
