Re: Qt6 (i686): Illegal Hardware Instruction

Yep, not astominishing: Qt6 has a complicated build system and makes use a lot of SSE(2) etc.
I assume you are running the i686 subarchiteture and some SSE2 opcodes krept into the binaries.
I'll open a bug..

The problem lately is that SSE2 is the lowest ISA level on IA32, everything seems to start to
adapt into that direction. I personally don't expect new software to work on anything lower
anymore out of the box and the effort starts to get high to make it work on the i686 or/and i486
subarchitecture.
