I have written a better version of this PR: https://github.com/tinygo-org/tinygo/pull/4317 It's similar, but actually fixes the same issue on all architectures (including amd64 where we just haven't seen it happen yet).
It assumed the maximum alignment was equal to
sizeof(void*)
, which is definitely not the case. So this only worked more or less by accident previously.I found this bug while working on MIPS support, but it is also a bug on many other architectures like amd64 (which has a maximum alignment of 16 bytes, not 8 as would be assumed here).
This can be fixed in a better way, by adding a call-site attribute to the
runtime.alloc
call that stores the expected alignment (or something similar). But at least the current fix should be safe.(It might actually still be buggy, since amd64 has a maximum alignment of 16 instead of 8. This should be fixed later).
