Current gcc trunk (but not gcc 4.5.1) ICEs when linking cns_solve using -O2
-fwhopr -fwholeprogram. The reduced test case is attached and crashes as...
[MacPro:~/badlinkdir] howarth% gfortran -c -fdefault-integer-8 -w -O2 -fwhopr
-fwhole-program --save-temps array_reduced.f
[MacPro:~/badlinkdir] howarth% gfortran -c -fdefault-integer-8 -w -O2 -fwhopr
-fwhole-program --save-temps cns_reduced.f
[MacPro:~/badlinkdir] howarth% gfortran -c -fdefault-integer-8 -w -O2 -fwhopr
-fwhole-program --save-temps genic_reduced.f
[MacPro:~/badlinkdir] howarth% gfortran -r -nostdlib -o
cns_solve-1007222053.exe array_reduced.o cns_reduced.o genic_reduced.o
-DINTEGER='long int' -DCNS_ARCH_TYPE_LINUX -fdefault-integer-8 -O2 -fwhopr
-fwhole-program -w
In file included from :0:0:
array_reduced.f: In function ‘find52_.constprop.0’:
array_reduced.f:5:0: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
lto-wrapper: gfortran returned 1 exit status
collect2: lto-wrapper returned 1 exit status
The lto1 ICE doesn't occur if the optimization is reduced to -O1 or if the
-fwhole-program flag is omitted.

Mine. IPA-CP makes us produce
MEM[(<unnamed-signed:64>[0:] * restrict)&C.3242][__result_find52_49]
but nobody folds this (C.3242 is constant zero) because the access is likely
undefined.
