I can't reproduce this with 13k p****engers.

Actually only numbers beyond 262000 might produce strange results, since ware_t hold 24 bit of menge. The error is most liekly connected to something else. Or can you reproduce it with your savegame? Then I would need the savegame for debugging.

@KillFrenzy:
1) the BMP format makes the file so big; please use PNG or JPG instead, even GIF would be much better (might even fit the forum's limits for attachments)
2) even text could be used instead here - the screenshot says (in short): "****ertion failed - utils/cbuffer_t.cc line 94 - Expression: count>=0"
3) that download service is a little annoying (have to wait to get a download link) EDIT: link has been replaced
4) topic title changed to make it useful
5) edit: getting the savegame may be necessary to reproduce and analyze the problem

I can't reproduce the crash (with linux, gcc4).

I rather suspect an error in the finnish translations. Does this error happens with english too?

Yes it does... Im starting to think that the error is somewhere else now.

I could reproduced crashing with both release version and my compiled nightly version. (Windows GDI)
Language is not a problem, I tested this with English, Japanese, and German, but crashed in any cases.

As I said in another topic, this problem is being reported from time to time.

[edit]
Nightly versions on wernieman's site don't have this problem.
Maybe, they don't contain ****ert code.

But, Windows versions on SF, both GDI and SDL contain ****ert code.
And this causes the problem.

Code: [Select]
void cbuffer_t::printf(const char* fmt, ...)
{
	va_list ap;
	va_start(ap, fmt);
	int count = vsnprintf( buf+size, capacity-size, fmt, ap);
	****ert(count >= 0);
	if(capacity-size <= (uint)count) {

I seems the specifications of vsnprintf are different among different platforms.

make cbuffer_T somewhat dynamic to allow really large amounts at stations to be displayed

This seems to be working well. Thank you.

BTW, who need to read such a long list which is up-to-date all the time.
There is no bookmark to jump to the list of other freights. This is annoying.

I've observed the same thing with an own savegame. (102) Nightly
I can show it if its neccessary!

Is there any solution or some requierement to solve this problem?

please try whether the bug is present in a recent nightly version. then upload a savegame if the bug is there.
