            Bug ID: 21495
           Summary: Assignment inside an assert statement should issue a
                    warning
           Product: glibc
           Version: unspecified
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: jimis at gmx dot net
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---

Having an assignment inside an if statement causes "gcc -Wall" to issue a
warning "suggest parentheses". However this does not happen for assert()
statements, hiding behaviour that can cause subtle but nasty side-effects.
Example code:

    assert(param = NULL);

Compiling with gcc -Wall does not print any warning.
