Nonsense error from DM in Bug Reports

ID:104744
 
Nov 18 2010, 10:45 pm
BYOND Version:479
Operating System:Windows 7 Pro 64-bit
Web Browser:Firefox 3.6.12
Applies to:Dream Maker
Status: Deferred
This issue may be low priority or very difficult to fix, and has been put on the back burner for the time being.
Descriptive Problem Summary:
After a few times compiling GOA in DM, it appears to go insane and start throwing random errors.

I've tested my RAM a few times since this started happening and it doesn't seem to be unstable, and it only occurs when compiling from within DreamMaker, using dm.exe never has errors.

The error that shows up varies, but usually something like this:

(random included code file):(random line):error: /textlength/_dm_icon_getpixel/ //////////////////////////////////////////////////////////// client//////////UnrealHospital//textlength//textlength/ //////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////// tv1//fridge_top//Window//ch//ch//ch//ch//sideltop/silent/ sps//sps//sps//sps//sps//sps//sps//sps//WillFit// Supplyscroll//Supplyscroll//Supplyscroll//Supplyscroll// Supplyscroll//Supplyscroll//Supplyscroll//

After shutting down DreamMaker when it is in this state, it crashes, here's a report from WinDbg:

First chance exceptions are reported before any exception handling.
This exception may be expected and handled.

Numbered Steps to Reproduce Problem:
1) Open up GOA's main file in DreamMaker
2) Work on it for a bit, while compiling
3) Somewhere around the 6th-10th time compiling watch as it starts failing for no reason.

Code Snippet (if applicable) to Reproduce Problem:











Expected Results:



Actual Results:



Does the problem occur:

Every time? Or how often? Every time I'm in DM long enough.

In other games?

In other user accounts?

On other computers?



When does the problem NOT occur?



Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? (Visit http://www.byond.com/download/build to download old versions for testing.)



Workarounds:

Periodically restart DreamMaker

I've gotten this a few times myself. Seems to pop up after you've compiled the project multiple times. Definitely seems to be related to Windows 7.

Destroy, I haven't seen this issue occur yet, but I'll try to duplicate it to see if I get it too.



(On a site note, can you please add me through pager so I can talk to you for a minute?)

This is going to be very difficult to diagnose unless we can be supplied with some source that consistently causes the problem, as well as associated platform info. I don't think it's a minor enough to defer for now.

Ok, I did some further testing (It doesn't seem to trigger on plain compiles, only if the code changes -- I went through the file list and started unincluding different files to trigger it.)



This time I had windbg running the whole time, which seems to have let me catch the first error that leads to this.



HEAP[dreammaker.exe]: HEAP: Free Heap block e5b6168 modified at e5f24c8 after it was freed

First chance exceptions are reported before any exception handling.

This exception may be expected and handled.

ntdll32!RtlpBreakPointHeap+0x23:

Directly after that (and an error at the same location in every subsequent compile):

(1e7c.22ac): Access violation - code c0000005 (first chance)

First chance exceptions are reported before any exception handling.

This exception may be expected and handled.

Which also causes the error at exit:

I have minidump files from each time it stopped in this process if those will help.

Just bumping to say it still seems to happen in 481 -- at least my test of 'keep changing the included files and recompile a bunch' triggered something:



(14f8.4c0): Access violation - code c0000005 (first chance)

First chance exceptions are reported before any exception handling.

This exception may be expected and handled.

Leading into something pretty much the same as the last test if I let it continue and try to close DM:

(I didn't see any strange error messages from DM specifically, but there's definitely some sort of crash here.)

Which 481 build was it? There was a change to Dream Maker in a later minor build.

The about window says 481.1090, which is the same as the one currently listed on the download page. I can re-download it and try again if you want.

No need; knowing it's 1090 is enough for me to work with.
