i have found the same problem.  The way I worked around it was to declare
a new float variable, say fl_var, and use it to read in my data. See old
and new code below:

OLD CODE:

...
float *f_ptr;
...
f_ptr = (float *)calloc(...);
...
fscanf(file,"%f",f_ptr);
...
      ^----- gives the run time error

NEW CODE:
...
float *f_ptr, new_var;
...
f_ptr=(float *)calloc(...);
...
fscanf(file,"%f",&new_var);
f_ptr[i] = new_var;    /* i'm inside a loop here */
....
       ^------ this code works!!??

Well, I can't figure it! Nothing else was changed in the program to
make it work.  That is it DIDN'T like the address sent to it with
using just 'f_ptr' but DID like the address it got with '&new_var'.

Anyone else figure this out more?  Anyone from Borland about to tell
us how to fix this?
