            Bug ID: 3392589
           Summary: interminable macro recursion with current git/master
           Product: NASM
           Version: unspecified
          Hardware: All
                OS: All
            Status: OPEN
          Severity: normal
          Priority: Medium
         Component: Assembler
          Assignee: nobody at nasm.us
          Reporter: sezeroz at gmail.com
                CC: chang.seok.bae at intel.com, gorcunov at gmail.com,
                    hpa at zytor.com, nasm-bugs at nasm.us
     Obtained from: Built from git using configure

Minimal test case:

$ cat 1.asm
%ifndef _NO_PREFIX
        %macro _sym_prefix 1
        %define %1   _ %+ %1
        %endmacro
%endif

%ifmacro _sym_prefix
_sym_prefix myfunc
%endif  ; _sym_prefix

global myfunc
myfunc:
        ret

$ ./nasm -f elf 1.asm
1.asm:11: error: interminable macro recursion
^C
(have to Ctrl-C here.)
This worked fine up until nasm-2.14.03rc2.

$ ./nasm -f elf -D_NO_PREFIX 1.asm
(this one is OK, obviously)
