What did you do?

i run this command to build with garble: garble -literals -seed=random -tiny -debugdir=out build -ldflags "-s -w -H=windowsgui"

What did you expect to see?

compile it normally

What did you see instead?

i see these error:
panic: runtime error: index out of range [1] with length 1
