From b7740a6fe01d254d79291bbcbbc853e874eb41ef Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jos=C3=A9=20Valim?= Date: Thu, 23 Oct 2014 09:59:30 -0200 Subject: Fix cover bug on last expressions with empty clauses OTP-8188 introduced a fix for handling last expressions in expressions like case, try and friends. However the fix did not account that some of those expressions like receive may have no clauses (only an after clause), leading to a function clause error when cover compiling code with such expressions. --- lib/tools/test/cover_SUITE_data/b.erl | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'lib/tools/test') diff --git a/lib/tools/test/cover_SUITE_data/b.erl b/lib/tools/test/cover_SUITE_data/b.erl index 13f39b8cb9..0a418a58d8 100644 --- a/lib/tools/test/cover_SUITE_data/b.erl +++ b/lib/tools/test/cover_SUITE_data/b.erl @@ -1,5 +1,5 @@ -module(b). --export([start/0, loop/0]). +-export([start/0, loop/0, wait/0]). start() -> spawn(?MODULE, loop, []). @@ -12,3 +12,9 @@ loop() -> stop -> done end. + +%% This checks for a bug in expressions which have no +%% "main" clauses (only after and friends) followed by +%% a return value in the same line. +wait() -> + receive after 1000 -> done end, ok. -- cgit v1.2.3
