Insufficient data descriptors in format after reversion

Hi there,

I have this Fortran code (3 lines in the middle of a very large source file):

write ( *, '(a,4a20)' ) '  Col: ', ( ctemp(j2), j2 = 1, inc )
    write ( *, '(a)' ) '  Row'
    write ( *, '(a)' ) '  ---'
The first line number is 1834. The code compiles with a bunch of warnings of this nature: real*4 parameter passed to a subroutine that needs real*8 or vice versa. When it runs, however it gives me this runtime error:

At line 1834 of file fftpacks_prb.f08 (unit = 6, file = 'stdout')
Fortran runtime error: Insufficient data descriptors in format after reversion
*** glibc detected *** ./a.out: free(): invalid pointer: 0x09fe5908 ***
It also gives me a memory dump I don't understand.

Any help will be appreciated. Thanks, - A.
