PGI fortran has trouble with elpa_int_value_to_string()

It seems that the PGI compiler has problems with elpa_int_value_to_string(). The output of elpa2_print_kernels is consisting just of newlines:

[loh@miy01 build]$ ./elpa2_print_kernels 
 This program will give information on the ELPA2 kernels, 
 which are available with this library and it will give 
 information if (and how) the kernels can be choosen at 
 runtime
 
  ELPA supports threads: no
 
 Information on ELPA2 real case: 
 =============================== 
  choice via environment variable: yes
  environment variable name      : ELPA_2STAGE_REAL_KERNEL
 
  Available real kernels are: 
 
   
   
 
 
 Information on ELPA2 complex case: 
 =============================== 
  choice via environment variable: yes
  environment variable name      : ELPA_2STAGE_COMPLEX_KERNEL
 
  Available complex kernels are:
