If one looks at the dump, one sees a similar problem to PR 43018. For the first
allocate, one has:
D.1530 = (void * restrict) __builtin_malloc (16);
which makes sense: 4 * integer(4) = 16 byte. However, for the second allocate
one sees:
D.1532 = (void * restrict) __builtin_malloc (48);
which might be OK. However, the following is definitely invalid - and causes
here a segfault
(void) __builtin_memcpy ((void *) a.$data, (void *) &acsr, 48);
