I will check this patch tomorrow (Jan 24th) to make sure that it fixes the
problem on non-reduced test cases.

On x86_32, the problem occurs somewhat differently. All I did differently is
add "-m32".
It seems that on x86_32, the copy constructor

When you say segfault, I presume you mean abort?
When I use the debugger, the problem appears to be in the call to
new Parameters(*P);
On x86_64, the problem occurs as

Several simple examples for alignment in vectorization.
The notes in the file about which functions contain
GCC sometimes loses alignment information.
If we declare an aligned pointer type:
// These two lines work (together)
typedef real aligned_real __attribute__((aligned(16)));
typedef const aligned_real* SSE_PTR;
Then gcc generates aligned access here:
// This function uses ALIGNED accesses

Also, I just noticed that the error occurs only if -ftree-vectorize is turned
on.
