tinygo build -gc none fails #4275

Open pierrec opened 1 month ago

tinygo version 0.31.2 darwin/amd64 (using go version go1.22.3 and LLVM version 17.0.1)

tinygo build -gc none
ld.lld: error: undefined symbol: _runtime.alloc
>>> referenced by task_stack.go:75 (/usr/local/Cellar/tinygo/0.31.2/src/internal/task/task_stack.go:75)

error: failed to link /var/folders/lb/nhsppbxs5_v27pn_x3kf66wc0000gn/T/tinygo1324987751/main: exit status 1

Note it works fine if used in combination of -scheduler none

If you need a minimal garbage collector try -gc=leaking.

This is the intended behavior. And one more reason why we should probably just remove this option.
