IJ16735: COMPILING WITH -M LEAVES A TEMPORARY FILE IN THE TMP DIRECTORY

APAR status

• Closed as program error.

Error description

• When compiling with -M, the compile leaves around an empty temp
  file in the tmp directory.
  
  ===== COMPILE COMMAND:
  xlclang -E -M test.c
  
  ===== TESTCASE:
  $ cat test.c
  #include <stdio.h>
  
  int main()
  {
      printf("fertisch");
  }
  $
  
  
  ===== ACTUAL OUTPUT:
  $ mkdir tmp
  $ export TMPDIR=./tmp
  $ xlclang -E -M test.c
  test.o: test.c /usr/include/stdio.h \
    /opt/IBM/xlC/16.1.0/include2/aix/standards.h \
    /usr/include/standards.h /usr/include/va_list.h \

  $ ls
  test.c  tmp
  $ cd tmp
  $ ls
  xlcAStqLaad
  $
  
  ===== EXPECTED OUTPUT:
  Tmp file should not exist after compile
  

Local fix

• N/A
  

Problem summary

• USERS AFFECTED:
  Clients using the -M option are affected by this issue
  
  PROBLEM DESCRIPTION:
  The compiler driver program creates a temp file when dealing
  with ASM objects, however does not delete it afterwards.
  This leads to the creation of many temp files with 0 size that
  later have to be manually deleted by clients.
  

Problem conclusion

• The compiler driver program has been fixed to stop generating
  the 0 size temp files
  

Temporary fix
