https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64655 --- Comment #3 from Adrien Guinet --- I don't think this is a user error. Some attributes might be declared aligned inside a structure, without any specifications that every instanced objects must be themselves aligned on a specific boundary. Thi

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64655 --- Comment #5 from Adrien Guinet --- Moreover, the test case runs fine without any automatic vectorisation and crashes when it is applied, so from my point of view there is something wrong with this optimisation!
