I just tried to compile Suse Linux package bochs-2.2.1-6 with a recent
GNU C++ compiler version 4.2 snapshot 20060225.
The compiler snapshot said
g++ -c -I. -I./. -Iinstrument/stubs -I./instrument/stubs -O2 -g
-fmessage-length=0 -D_FORTIFY_SOURCE=2 -fpermissive -D_LARGEFILE_SOURCE
-D_LARGEFILE64_SOURCE -pthread `sdl-config --cflags` `wx-config --cxxflags`
-I/opt/gnome/include/gtk-2.0 -DBX_PLUGIN_PATH="\"/usr/lib64/bochs/plugins\""
-DBX_SHARE_PATH='"/usr/share/bochs"' logio.cc
logio.cc:277: internal compiler error: in add_virtual_operand, at
tree-ssa-operands.c:1867
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
Preprocessed source code attached. Flags -fpermissive and -O2 required.

------- Comment #2 from pinskia at gcc dot gnu dot org 2006-02-26 22:38 -------
Reducing (I have a code that already does not need -fpermissive).

------- Comment #3 from pinskia at gcc dot gnu dot org 2006-02-26 23:06 -------
Confirmed, reduced testcase:
typedef struct logfunctions {
char *prefix;
int onoff[5];
}a;
extern int default_onoff[5];
void f(a *t)
{
int i;
for (i=0; i<5; i++)
t->onoff[i] = default_onoff[i];
}
-------
For some reason it is only reproduciable with 64 bit targets.

I think this will be solved with the patch which solves PR 26443 as the ICE is
also in VRP2.
