Internal compiler error when compiling with C++ with -O2, gcc 2.95.2, i686-pc-linux-gnu

[Pieter van Prooijen]

Hello gcc developers,

I've encountered a bug when compiling a certain cpp file with the following 
options:
(Compiling with -O0 or -O1 does work allright)

cc -v --save-temps -c 
-I/home/pieter/projects/SeriesIII/Libs/stl_sgi_320/include 
-I/home/pieter/projects/SeriesIII/Libs/ACMapLib/include 
-I/home/pieter/projects/SeriesIII/Libs/Win32Compat/include 
-I/home/pieter/projects/SeriesIII/Libs/GridNet/include 
-I/home/pieter/projects/SeriesIII/Libs/ACUtils/include 
-I/home/pieter/projects/SeriesIII/Libs/BookLib/include 
-I/home/pieter/projects/SeriesIII/Libs/diblib/include 
-I/home/pieter/projects/SeriesIII/Libs/zlib/include 
-I/home/pieter/projects/SeriesIII/Libs/FreeType/include -O2 -Wall 
-Wno-reorder -Wno-unknown-pragmas -Wno-shadow  -o 
../objects/LinuxDynRelease/layroad.obj ../source/layroad.cpp

The output generated was the following:
