Error during redisplay: (jit-lock-function 1) signaled (error "prism: Infinite loop detected in ‘prism-match’. Please report this bug")

Recently, I've started running into difficulties using julia-mode in combination with prism.

On my machine, prism-mode struggles with the following minimal julia file:

"""asdf
    qwer
"""
sum([1,2])

It raises the following error in the *Messages* buffer:

Error during redisplay: (jit-lock-function 1) signaled (error "prism: Infinite loop detected in ‘prism-match’ (buffer:#<buffer mwe.jl> point:2).  Please report this bug")

However, I don't think this is an error in prism-mode, as it is perfectly fine with the following multi-line comment in python (where julia-mode is inactive):

"""asdf
   qwer
"""
print("Welcome to Scaler!")

Hi @YueRen. Please report this to prism or provide more detail on how this is a bug in julia-mode (e.g. a stacktrace showing how julia-mode is incorrectly causing an infinite loop in prism-match). We aren't in a position to be figuring out why an external package is raising an error without more information than this.

@non-Jedi Sorry for the late reply. This indeed seems more like a bug with prism, so I will close this ticket for now. I may reopen this, in case something in julia-mode is causing the failure and I figure out what.

Quick update, I was using prism-mode wrongly. In case anybody runs into the same error, here is the solution:
