What can cause a segmentation fault besides pointers? I've been getting=20
one that resists all attempts to track down its cause.
The problem persisted after I eliminated all pointers to the variable tha=
t=20
seems to be causing it. (I made the function return the value instead of=20
modifying it directly)
There is some recursion involved, but as far as I can tell, it isn=E2=80=99=
t being=20
called before the fault.
I have determined that the memory location of this variable /is/ being=20
changed before the crash. However, when I attempted to locate exactly whe=
re=20
in the code it is being changed using printf(%p,foo), the crash didn=E2=80=
=99t=20
happen. (Heisenburg meets Ritchie?)
The fault seems like it might be dependent on the contents of a file I=E2=
=80=99m=20
viewing (ASCII text). Some files can be read without crashing; others=20
cannot. Other than that, I have no clue.
