There is some kind of bug associated with use of x and t formats
together. See example below. Counting characters, you can see the 1st line
of output is wrong, while the 2nd and 3rd lines are correct. If the 1x
is omitted from the format, the output is correct.
This bug is observed both with Windows 20061021 version, and
linux-X86_64 20070305 version of gfortran.
-------------------------------------------------------------------
C:\source\test>type tft.f95
program t
integer, parameter :: N = 9
character(len=40) :: fmt
character(len=2), dimension(N) :: y
y = 'a '
fmt = '(a,1x,(t7, 3a))'
write(*, fmt) 'xxxx', (y(i), i = 1,N)
end program t
C:\source\test>gfortran -o tft tft.f95
C:\source\test>tft
