Bus Error!?

Hello -

I have started coding C since September and am trying to compile a
program which works as a very rudimentary code breaker (utilizing
english language letter frequencies).

I have managed to find the letter frequencies of a document and sort
them - but was trying to find a way to read the input (which was
originally stdin from the keyboard) a second time in order to replace
the original letters with new letters.

It was suggested that I read from a second file in the same directory
using fopen and fgetc to read it - but when i try that I am getting a
bus error. Yet it seems to work when compiled on a windows system.
What might I be doing wrong? I can send the code if that is helpful.

Thanks -
Daniel

Very difficult to tell without looking at the code. But when you read
in the data make sure you are not reading in more data than you have
space for. That is if you have a buffer of 10 and read in 11
characters bad stuff happens. Are you working on this in XCode ? If so
in the debugger when this happens the debugger will halt and show you
the program stack at the failure. At the top will be functions in the
C library or system that will dump in ASM code, lower down will be
stuff you wrote. It will show you the line where you have an error.
You can then poke around to see what might be happening.
