My application gets an unaligned access error when I attempt to run with v9 compilers. Curiously, no error occurs if I compile v8 / run v8, compile v9 / run v9, or compile v9 / run v8.
v8 =
ifort -V
Version 8.1 Build 20041021 Package ID: 1_fc_pu_8.1.021

The offending code is noted below:
character*37 NOTESMSG(21)
character*37 NOTES(100)
character*2 str
integer i,j
...
write (str, 270) j
NOTES(i) = NOTESMSG(3)
NOTES(i)(8:9) = str <- unaligned error here
270 format(i2)
The portion of the code is quite old and this construct is used extensively. This error has never occurred before with other versions of OS/compiler. Also, the error happens to some of the assignments but not all of them. Is it an issue with a char*2 being considered a 2-byte element?
Thoughts?
