[Bug c/25602] New: internal compiler error while bootstraping (while compiling libobjc/sendmsg.c)

[alex at milivojevic dot org]

I was bootstrapping gcc-4.0.2 on Solaris 2.9 system.  Since I wanted to build
64-bit compiler binary, and I didn't had compiler capable of producing 64-bit
code, I did it in two stages.

The first stage built and installed fine.  I built 32-bit gcc-4.0.2 binaries
using following commands:

$ ../configure --prefix=/home/amilivojevic/s9
--with-local-prefix=/home/amilivojevic/s9 --with-cpu=ultrasparc
--with-tune=ultrasparc --enable-languages=c
$ gmake bootstrap

(I know what --with-local-prefix does, and I really wanted it that way).

Then, I used this temporary installation to build 64-bit gcc binary:

$ CC="gcc -m64" ../configure sparc64-sun-solaris2.9 --prefix=/opt/pbl
--with-local-prefix=/opt/pbl --with-cpu=ultrasparc --with-tune=ultrasparc
$ gmake bootstrap

The bootstraping started fine, but at one point I got "internal compiler
error".  This is output with '-v -save-temps added' including full command
line.  I'm not sure in what stage this was (but it was already using temporary
64-bit compiler binary to recompile itself):
