> Fixed (the testcase with aligned(1)). The original is INVALID.
The testcase with aligned(1) cannot pass on strict-alignment targets, either
with or without vectorization. On the SPARC:
(botcazou@nile) /nile.build/botcazou/gcc-head/sparc-sun-solaris2.8 $ ./pr48377
Bus Error (core dumped)
On IA-64:
(botcazou@merced) /nile.build/botcazou/gcc-head/ia64-linux-gnu $ ./pr48377

Please move it to gcc.target/i386 or something equivalent.
