IV31633: XLF ERROR IN SINGLECONVERSION

November 2012 PTF for XL Fortran for AIX, V14.1
March 2013 PTF for XL Fortran for AIX, V14.1

APAR status

• Closed as program error.

Error description

• The following testcase fails to compile:
  
  
  % cat test.f90
  
       character(len=1) :: h(1:100) = (/ ( (' ',i=1,9), '|',
  j=1,10) /)
       print *, h
       stop
       end
  
  % bgxlf90 -o test test.f90
  "test.f90", line 1.46: 1517-005 (U) Error in SingleConversion.

  1501-511  Compilation failed for file test.f90.
  

Local fix

• Workaround 1:
  
  
  Get rid of the nested ac-implied do.  i.e. change the code to
  the following:
  
       character(len=1) :: h(1:100) = ' '
       h(10:100:10) = '|'
  
  Workaround 2:
  
  Separate array construction from declaration.
  
       character(len=1) :: h(1:100)
       h = (/ ( (' ',i=1,9), '|', j=1,10) /)
       print *, h
       stop
  

Problem summary

• Compilation may fail due to ICE when processing nested
  array-constructors in static initialization.
  

Problem conclusion

• The problem had been fixed.
  

Temporary fix
