            Bug ID: 3392612
           Summary: %exitrep exits *after* the current rep
           Product: NASM
           Version: 2.14.xx
          Hardware: All
                OS: All
            Status: OPEN
          Severity: normal
          Priority: Medium
         Component: Assembler
          Assignee: nobody at nasm.us
          Reporter: jadoxa at yahoo.com.au

Exiting a macro repeat still executes the current loop.

> type tst.nsm
%macro testrep 0.nolist
  %assign i 1
  %rep 4
    %if i==3
    %warning i
    %assign i i+1


> nasm -e tst.nsm
%line 11+1 tst.nsm

tst.nsm:12: warning: (testrep:7) 1 [-w+user]
tst.nsm:12: warning: (testrep:7) 2 [-w+user]
tst.nsm:12: warning: (testrep:7) 3 [-w+user]

"3" should not be output, as that occurs after the exit.  I believe this can be
fixed by making "in_progress = 0" in the PP_EXITREP case.
