Vim randomly stops when go_highlight_function_calls is on

[adirizka7]

What did you do? (required: The issue will be closed when not provided)

My vim would randomly stops and I had to kill the process when opening certain files with go_highlight_function_calls enabled. If it doesn't stop, vim also becomes extremely laggy.

What did you expect to happen?

Vim should not stop and should not be laggy when go_highlight_function_calls is enabled.

What happened instead?

Vim randomly stops and becomes laggy.

What does set re? output?

The output is regexpengine=1

Try changing it to 0 or 2. I use 0, but sometimes it has to be forced to use the new engine by setting it to 2.
