------- Comment #1 from burnus at gcc dot gnu dot org 2007-06-05 17:27 -------
The error message is ok as you have the string "\" + "0", which does not fit
into a character(len=1) variable. bzero(4) contains "\", which is consistent
with several compilers.
-fbackslash implies that C-style control character syntax is accepted, however,
then \0 should be achar(0) not achar(92). Currently, gfortran accepts by
default (unless -fno-backslash is used) "\n" as new line, but not \0 as
achar(0) which is rather inconsistent. (g95 does the same; ifort offers -assume
bscc, using which achar(0) is returned.)
Work around (works with all ocompilers, Fortran 90 syntax):
character(len=1), parameter :: charZero = achar(0)
data bzero /'0', '.', '0', charZero, '0'/
