[julia-users] using ccall to call a fortran parser for large input file

[benjamin kary]

I have a Fortran module which parses a complicated input file to populate a 
workspace with all the variables I need for a certain task.  I have 
decimated the fortran code to try and get a single parsing command to 
work.  The input to the Fortran function "em_data_read_input" is a string 
containing the name of the input file.  The Fortran function returns a 
variable "freq" of type REAL(kind=8).  The following causes the julia 
kernel to restart with no error message:

test = ccall( (:__global_variables_MOD_emdata_read_input, "libglobvar"), 
Float64, (Ptr{Int8},), "csem3dfwd.in" )

Is there anything obviously wrong with what I'm trying to do?

Thanks,

Ben
