APAR status

• Closed as program error.

Error description

• An internal compiler error is encountered when using the
  -qinclude option to include a header file in a source file that
  contains an invalid preprocessor directive.  The error occurs
  when using -qsource and -qshowinc to generate a source listing
  of the resulting preprocessed source.
  
  The error is sensitive to small code changes including physical
  source file size, comments, ordering or nesting of included
  files.
  
  A cut-off, partial -qsource listing file may be output.
  
  
     === EXAMPLE ===
  
  Note:  not a compilable example
  
  header.h:
  #define some_define 1
  
  /*
  
  */
  
  #include <some_header.h>
  
  
  source.c:
  #badpre
  
  int main(int argc,char *argv[]) {
   return 0;
  }
  
  
  
  $ xlc test.c -I. -qsource -qshowinc -qinclude=header.h
