From 6348e861b20d0b90275970af7357ac35ef956f16 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 3 Apr 2018 00:40:25 +0800 Subject: parser: Fix parsing of ${} dash -c 'echo ${}' should print "Bad subtitution" but instead fails with "Syntax error: Missing '}'". This is caused by us reading an extra character beyond the right brace. This patch fixes it so that this construct only fails during expansion rather than during parsing. Fixes: 3df3edd13389 ("[PARSER] Report substition errors at...")
