I get the error only if I use -O3.
But the two bugs are related.
Last checked rev#141779

[Bug c/37955] New: internal compiler error: in vectorizable_store, at tree-vect-transform.c:5447

[alon dot barlev at gmail dot com]

Attached is a sample from OpenSSL.
When compiled with -O3 the error comes up.

I tried to remove as much code as I could, but it looks like every line I
remove also avoid the error.

I use rev141361

Maybe the complete source will be better...

Still:

e_aep.c: In function ‘aep_get_connection’:

See <http://gcc.gnu.org/bugs.html> for instructions.

Using binutils CVS head and gcc head (rev#141655).

How can I help more than this?
Can you send a patch to provide some more information?
