Hi! This small list comprehension works fine in R12B-5, but not in R13B01
-module(alphanum).
-export([orgno_alphanum/1]).
orgno_alphanum(OrgNo) ->
[C || C <- OrgNo, ((C >= $0) andalso (C =< $9))
orelse ((C >= $a) andalso (C =< $z))
orelse ((C >= $A) andalso (C =< $Z))].
Trying to compile:
mrtin@REDACTED:~$erlc alphanum.erl
Function: '-orgno_alphanum/1-lc$^0/1-0-'/1
./alphanum.erl:none: internal error in v3_codegen;
