    rts: Fix data-race in hs_init_ghc · 3e3a6be4
    Ben Gamari authored and Cheng Shao's avatar Cheng Shao committed 
    As noticed by @TerrorJack, `hs_init_ghc` previously used non-atomic
increment/decrement on the RTS's initialization count. This may go wrong
in a multithreaded program which initializes the runtime multiple times.

Closes #22756.
