panic: runtime error: unsafe pointer conversion (Go 1.14) #187
Description
In Go 1.14 there is now checks of pointer conversions with the requirement that they should align to the "natural size".
It seems like they decided to make this enabled when -race is specified: golang/go#34964
This leads to crashes like this:
