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.

------- Comment #4 from pinskia at gcc dot gnu dot org  2006-02-26 23:09 -------
I think this will be solved with the patch which solves PR 26443 as the ICE is
also in VRP2.

Confirmed, fixed with the patch for PR 26443.
