This is an issue from Fujitsu testsuite.
The execution of a program compiled by flang-new terminates with a fatal error.
In the program, there is a `PRINT` statement with Implied DO. The format of it has a repeat specification. If parentheses are used with the repeat specification, the error occurs. The error doesn't occur without parentheses.
The following are the test program, Flang-new and gfortran execution result.
```fortran
! test.f90
REAL ANSTBL(50,3)
PRINT '((I2,3(D25.16)))', ( J,ANSTBL(J,1),ANSTBL(J,2),ANSTBL(J,3), J=1, 50 )
!PRINT '((I2,3D25.16))', ( J,ANSTBL(J,1),ANSTBL(J,2),ANSTBL(J,3), J=1, 50 )
END
```
```console
$ flang-new -v test.f90
