This is also a problem at tip.

It's the really big pinyin_dict.go file. Compiling the initializer for PinyinDict fails. It has a 20,000 line map initializer, and that function has too many stack slots (~20,000) times blocks (125,000). The resulting live bitmap is too big.

There are things we can do that might fix this, like #26552. Unfortunately, they will be 1.12 at best.

But if you want to make progress now, you might try reorganizing your code. Use a slice as the underlying data structure and copy it into a map in an init function. Presumably that code is autogenerated so it might require only a small change to the generator.

@randall77 Thanks for your answer, i put it into func init(), and it works for now.

@randall77 - Since OP has resolved the issue, do we want to track this separately or mark as dup of #26552 ?

Let's track this separately. #26552 might fix it but I'm not sure.

This seems fixed at tip. CL 140301 helped, but even without that CL tip can compile the OP's code (which is now the commented-out initializer in that github repository, right?). So something else has helped also, not sure what. It does still take ~4GB or so to compile, but the live variable map is not >2^31 any more.

I'm going to close this now. #26552 might help some more, but we're ok for now.
