This behavior using Fortran with the sacio.a library is a known one
and only discovered about one month ago. Hopefully this will be
fixed in the next release.
A possible workaround is to include the C string terminator at the
end of your character string in Fortran. In C this character is '\0'
and I believe it is char(0) in Fortran.
Cheers,

I'm having trouble with a Fortran program that I inherited, that
reads in information from a text file, makes some calculations, and
writes the results into an existing SAC blackboard file.
The program appears to compile okay (though I have to use the -m32
option in the makefile as I've recently moved to a 64-bit Linux
platform). When I try to run it, however, it seems to be successful
in reading the blackboard file, but crashes with a "Segmentation
Fault" as soon as it gets to the first "setbbv" command. I've tried
writing a short test program or two with blackboard variables in
Fortran - seems that it's okay on subroutines such as "readbbf" and
"getbbv", but always gives a segmentation fault whenever I write
anything that includes a "setbbv".
I tried looking at the example on the SAC2000 user manual, but am
none the wiser. Also having trouble understanding how the getbbv
subroutine retrieves the blackboard variables - no segmentation
faults, but I've yet to get a meaningful answer when I try to use
it on an existing BBFILE.
