Weird runtime error

[Tim Johansson]

When i run my program, i get the following:

"Exiting due to signal SIGSEGV
General Protection Fault at eip=0001cdc0
eax=00000009 ebx=000ca110 ecx=000ca110 edx=00000000 esi=0000160e
edi=00000009 ebp=000c99f8 esp=000c99e0 program=C:\TEST.EXE
cs: sel=01a7 base=029d0000 limit=000dffff

Call frame traceback EIPs:
0x0001cdc0
0x0001c46e
0x00001757
0x00005548
"

That makes no sense at all to me... Does anybody know what the error is? I'm
using DJGPP as compiler, by the way.

You deleted a pointer twice, read or wrote memory you weren't supposed to,
dereferenced a null pointer, or some other pointer related error most
likely.
Try stepping through your program and see exactly when it crashes, then work
backwards.

Try piping it through the debugger, I think there is a version of GDB
for windows, although I'm not sure. Anyways a backtrace or BT in GDB
would give you a good hint as to where to start looking.
