Format syntax error

In my application I obtain a format syntax error, but I  do not recognize why.

I created a minimal example:

program test
  implicit none
  character(len=200) :: formatstr
  character(len=*), parameter :: formatstr2 = '("test",I2.2,"")'

  formatstr = formatstr2
  write(*,'(A)') formatstr
  write(*,'(A)') formatstr2
  write(*,*) formatstr == formatstr2
  write(*,formatstr2) 12
  ! the next line creates an error
  write(*,formatstr) 12

end program test

I obtain the following output:

> ifort -g -traceback test2.f90> ./a.out
("test",I2.2,"")
("test",I2.2,"")
 T
test12
forrtl: info (58): format syntax error at or near ")
forrtl: severe (62): syntax error in format, unit -1, file /dev/pts/4

I tested this with the Intel Fortran Compiler 15.0.1 on a 64bit Linux and with some older version.
The code seems to work fine with both the GNU Fortran compiler (gfortran) and the PGI Fortran compiler (pgf90).

It also works when I change the format string to ("test",I2.2) or ("test",I2.2,"test"),
but in my application the formatstring is generated and thus one may obtain an empty string there.
