Subject: cmd/compile: fix mis-compilation for static array initialization
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=dae71067ce7ee41ebe752a4ee3c544506e74f824;p=gostls13.git

cmd/compile: fix mis-compilation for static array initialization

The bug was first introduced when the compiler is still written in C,
with CL 2254041. The static array was laid out with the wrong context,
causing a stack pointer will be stored in global object.

Fixes #61730
Fixes #77193
