[Bug go/79281] gccgo: Binaries using goroutines crash on m68k

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79281 --- Comment #4 from James Clarke --- Ah, sorry, there's a separate C implementation of all this. I imagine it's the bools in "struct M" in runtime.h messing it up, so "struct Note" and "struct Lock" need __attribute__((aligned(4))) on their key

[Bug go/79281] gccgo: Binaries using goroutines crash on m68k

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79281 --- Comment #3 from James Clarke --- I believe the problem is in the "m" type in runtime2.go. There are 4 bools in a row, which is fine, as they will take up 4 bytes, but then "printlock" is an int8, which means "fastrand" will only be 2-byte
