Bug#358755: g++-4.0: G++ drops const int arrays

[Markus Schaber <schabi@logix-tt.com>]

Package: g++-4.0
Version: 4.0.3-1
Severity: normal

Hi,

G++ seems to drop const int arrays, while gcc compiles them correctly.

See the following example of the two attached files:

gcc -Wall -c gen_array.c
gcc -Wall -o gen_array gen_array.o
./gen_array > array.cc
g++ -Wall -o array.cc.o -c array.cc
ls -l array.cc.o
-rw-r--r--  1 schabi schabi 638 Mar 24 11:19 array.cc.o
./gen_array > array.c
gcc -Wall -o array.c.o -c array.c
ls -l array.c.o
-rw-r--r--  1 schabi schabi 4735 Mar 24 11:19 array.c.o


array_cc.o should also be more than 4000 bytes large, because the array
contents itsself are 4000 bytes. GCC seems to translate it correctly.

Thanks,
Markus
