[Bug c++/23491] [4.0/4.1 Regression] new declarator with constant expression gives "error: invalid use of array with unspecified bounds"

[pinskia at gcc dot gnu dot org]

------- Additional Comments From pinskia at gcc dot gnu dot org  2005-08-20 02:20 -------
In 4.0.0, we reject the code:
t.cc: In function ‘void f(int)’:
t.cc:9: error: invalid use of array with unspecified bounds


On the mainline we ICE:
t.cc: In function ‘void f(int)’:
t.cc:9: internal compiler error: in assign_stack_temp_for_type, at function.c:594
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Both 4.0 and 4.1 were compiled with checking.
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: /home/peshtigo/pinskia/src/gnu/gcc/src/configure --target=i686-pc-linux-gnu --
host=i686-pc-linux-gnu --enable-__cxa_atexit --enable-languages=c++,objc,java,f95 --prefix=/
home/gates/pinskia/linux --enable-threads=posix --enable-shared
Thread model: posix
gcc version 4.1.0 20050819 (experimental)

Though without checking we don't get an ICE:
t.cc: In function 'void f(int)':
t.cc:9: error: invalid use of array with unspecified bounds
t.cc:9: error: invalid use of array with unspecified bounds
t.cc:9: error: invalid use of array with unspecified bounds
t.cc:9: error: invalid use of array with unspecified bounds
