[Pkg-erlang-devel] Bug#756515: erlang-edoc: edoc crashes on valid Erlang source with tricky macro

[Balint Reczey]

Package: erlang-edoc
Version: 1:17.1-dfsg-4
Severity: normal

Dear Maintainer,

The following small Erlang source file crashes edoc in the way listed below:

$ cat edocbug.erl -module(edocbug).

-export([bar/1]).
-define(FOO(), a -> ok).

bar(A) ->
    case A of
    ?FOO()
    end.

$ erlc edocbug.erl $ erl
Erlang/OTP 17 [erts-6.1] [source] [64-bit] [smp:4:4] [async-threads:10]
[kernel-poll:false]

Eshell V6.1  (abort with ^G)
1> edoc:file("edocbug.erl").
edocbug.erl: at line 9: syntax error before: 'end'
** exception exit: error
     in function  edoc:'-check_forms/2-fun-0-'/2 (edoc.erl, line 770)
     in call from lists:foreach/2 (lists.erl, line 1336)
     in call from edoc:read_source/2 (edoc.erl, line 660)
     in call from edoc_extract:source/3 (edoc_extract.erl, line 52)
     in call from edoc:read/2 (edoc.erl, line 538)
     in call from edoc:file/2 (edoc.erl, line 116)

Cheers,
Balint
