Crash Offsets
-
@Nightstalker: That function already tests if its input is 0 or -1, so you must have a major bug if it’s failing. Unfortunately, all I can tell you is that it’s called (at least) from GetRoot and IsDescendant.
@Helloween: EAX is the index; EDX is the base and the reason for the crash. It creates a list of items (not sure what, possibly ship types), but it expects at least one item; the crash occurs when there are no items. Here’s a patch that seems to work: content.dll, 0C456A, 07->2A. Of course, that just hides the problem, it doesn’t fix it.

Ah edx. thx.
I will try the fix at home
-
It only fails intermittently (No pattern that I can find, ranges from once every two weeks or can go a month or more sometimes), usually in intense NPC combat or PVP. GetRoot and IsDescendant, does this refer to sur files??

brrr if esi<=esi then jump?

@Nightstalker: I sympathize, such intermittent bugs are hard to track down. GetRoot accepts a CObject* and returns a CObject* (presumably a parent relationship). IsDescendant takes two longs (presumably hashes) and returns bool (the first object is a descendant of the second).
@Alex: Looks like you have a good without an equipment line.

Why sorry? I trying to learn
Thx, will take a note.
drops assembler reference from window
-
TEST is an AND that discards the result. ANDing something with itself yields itself, but affects the flags. It is commonly used as a short way to test for zero, but it can also test for negative numbers, when the high bit is set. So test reg,reg preserves reg, clears the carry flag and sets the zero and sign flags accordingly.
-
Reading old paper tutorials, but without good reference hard to understand…
What assembler reference you will recommend?
-
I use these two:
Intel Architecture Software Developer’s Manual - google it, 3 pdfs.
http://faydoc.tripod.com/cpu/oh, there’s actually third in my bookmarks: http://ref.x86asm.net/

Thx again, server much stable x)
server.dll, 0076fdf
?get_behavior_id@IObjInspectImpl@@UBEHXZ
Wrong behaviour? Right?
-
It seemed we have corrected all errors, but now happens only
ntdll.dll, 00011689
Os error?
Debug shows

I have a problem to get more information ;(
I have a crash at 0x0004f486 in common.dll that appears very often. With a dll viewer the address should be somewhere between:protected: virtual __thiscall CObject::~CObject(void) 0x062af440 0x0004f440 565 (0x235) Common.dll D:\Games\Freelancer\EXE\Common.dll Exported Function
and
public: unsigned int __thiscall CObject::AddRef(void) 0x062af600 0x0004f600 1197 (0x4ad) Common.dll D:\Games\Freelancer\EXE\Common.dll Exported Function
Am i on the right was assuming that it must be somewhere either in destroying an object or adding a reference (whatever ref is meant with it)? Because that are the addresses situated next to the crash offset.
Is there a way to get to the direct address that is crashing? Windbg? Any other tool?
-
Related to ntdll.dll - not supported/equipable archetype in players char file.
Use Player Cleaner or DSAccount manager with all check options on.
-
Is there any possibility to get a kind of callstack of a current happended crash? It would be nice if its logged somewhere in a file… I have tried to debug a crash offset (by using breakpoints) but the routine is way too much called to trigger any crash reason ;(
So actually when the crash happens and having the callstack would be a really great…
