Public bug reported:
Binary package hint: gcc
This appeared recently when upgrading from gutsy to intrepid. Compiling
the following with g++
void toto1(double*const __attribute__((aligned(16))) X);
void toto2(double* const (&X)[1]);
produdes
g++ -c -o test.o test.cc
test.cc:2: error: alignment of array elements is greater than element size
Observe the `2' in the error message, the error is reported for toto2.
(For toto1 an error would be acceptable, I think).
But even worse, if we take
void toto0(double* const (&X)[1]);
void toto1(double*const __attribute__((aligned(16))) X);
void toto2(double* const (&X)[1]);
All three prototypes compile flawlessly.
This particular testing was done with 4:4.3.1-1ubuntu2 on an 8.10 amd64,
but we observed the same thing on 8.10 i386
Previously, everything was working well on 8.04.
