Subject: [PATCH] gnulib/regexec: Resolve unused variable
|
||||
|
||||
This is a really minor issue where a variable is being assigned to but
|
||||
not checked before it is overwritten again.
|
||||
|
||||
The reason for this issue is that we are not building with DEBUG set and
|
||||
this in turn means that the assert() that reads the value of the
|
||||
variable match_last is being processed out.
|
||||
|
||||
The solution, move the assignment to match_last in to an ifdef DEBUG too.
|
||||
|
||||
Fixes: CID 292459
