FORTRAN error *** glibc detected ***

Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:

I'm doing aproximation of derivative called five-point stencil. For every value of x, in interval [a,b], in step of 0.1 i need to calculate derivative.

2. Relevant commands, code, scripts, algorithms:

The equation is like this:

Code:

Five-point stencil:
(-f(x + 2h) + 8f(x + h) - 8f(x - h) + f(x - 2h))/(12*h)
---> (-first+8*sec-8*third+fourth)/12*h

I want to calculate every of theese, so first, sec, third.... expression and then at the end calculate derivative.

3. The attempts at a solution (include all code and scripts):

Code:

variables = 'x'
x=a+2*h
do while(x<=b)
variablesvalues=x
x=x+delta
call recog_variables (func, variables)
first(i)=evaluate(variablesvalues)
print*,'to je',first(i)
i=i+1
call destroyfunc()
end do



x=a+h  !without this, program works, prints first(i), but it doesn't print sec(i).

do while(x<=b)
variablesvalues=x
x=x+delta
call recog_variables (func, variables)
sec(i)=evaluate(variablesvalues)
print*,'to je',sec(i)
i=i+1
call destroyfunc()
end do

mkdtemp

MKDTEMP(3)						     Linux Programmer's Manual							MKDTEMP(3)

NAME

       mkdtemp - create a unique temporary directory

SYNOPSIS

       #include <stdlib.h>

       char *mkdtemp(char *template);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       mkdtemp():
	   /* Since glibc 2.19: */ _DEFAULT_SOURCE
	   || /* Glibc 2.19 and earlier: */ _BSD_SOURCE
	   || /* Since glibc 2.10: */ _POSIX_C_SOURCE >= 200809L

DESCRIPTION

       The  mkdtemp()  function  generates a uniquely named temporary directory from template.	The last six characters of template must be XXXXXX
       and these are replaced with a string that makes the directory name unique.  The directory is then created with permissions 0700.  Since	it
       will be modified, template must not be a string constant, but should be declared as a character array.

RETURN VALUE

       The mkdtemp() function returns a pointer to the modified template string on success, and NULL on failure, in which case errno is set appro-
       priately.

ERRORS

       EINVAL The last six characters of template were not XXXXXX.  Now template is unchanged.

       Also see mkdir(2) for other possible values for errno.

VERSIONS

       Available since glibc 2.1.91.

ATTRIBUTES

       For an explanation of the terms used in this section, see attributes(7).
