Fix msan uninitialized-read error in sstring.c #21

Closed jlebar closed 1 year ago

jlebar commented 2 years ago

With msan and fpesan, msan detects that XS->C is not initialized. I'm not sure why we need fpesan, but maybe it's necessary to block an optimization. (My test is too large to run without -O2.)
