ash: parser: Fix parameter expansion inside inner double quotes

2018-04-02T19:00:59+00:00

Upstream email: parser: Fix parameter expansion inside inner double quotes The parsing of parameter expansion inside inner double quotes breaks because we never look for ENDVAR while innerdq is true. echo "${x#"${x+''}"''} This patch fixes it by pushing the syntax stack if innerdq is true and we enter a new parameter expansion. This patch also fixes a corner case where a bad substitution error occurs within arithmetic expansion. Reported-by: Denys Vlasenko Fixes: ab1cecb40478 (" parser: Add syntax stack for recursive...")
