SIGTRAP after SetText()
« on: June 29, 2011, 08:32:03 pm »
Hello there,
I have a little problem here and I hope that somebody can help me. I have been working on a game for quiet some time now and everything seemed to work fine. I'm not home for a couple of weeks now, but I wanted to continue working on my game. So i brought all the files with me and set everything up on a different computer. The program compiles just fine. But when i tried to fire up the debugger a weird thing happened. The program just crashed out of nowhere at start up. All the debugger was saying was:
Code: [Select]
Program received signal SIGTRAP, Trace/breakpoint trap.
In ?? () ()
Debugger finished with status 0

Of course that is useless as could be. The call stack did show anything interesting either. So I tried different things, but none of them seemed to work at all. Then i had the idea to update my IDE (i am using Code::Blocks 10.05). So i downloaded the debugger nighly (26 June 2011 build (rev 7257)). I still got the same error, but this time the debugger messages were a little more detailed. This time the call stack looked like this:
Code: [Select]

#16 00409629 CMainMenu::Init(this=0x15e8880) (..\Src\MainMenu.cpp:9)

The part of the code that the error is referring too looks like this:
Code: [Select]
In the header file:
sf::String creditsHeader;

and in the .cpp file:
creditsHeader.SetFont(sf::Font::GetDefaultFont());
creditsHeader.SetText("Credits");
creditsHeader.SetSize(80);

So I am really lost on this one and I don't know anything more that I could try... I hope somebody can help me.

Here are some more information on the system and versions:
Windows XP SP3
SFML 1.6
gcc 4.5.2

It's a known bug, I would recommend using SFML2, its pretty stable and has a lot of bugfixes since 1.6. It's also really easy to install if you follow this guide:

SIGTRAP after SetText()
« Reply #3 on: July 05, 2011, 03:47:21 pm »
Thank for the replys, but sadly this doesn't help...
I tried to use a couple different fonts, but I still get the same error...
In my code it looks like this:
Code: [Select]
//first this
m_pHeaderFont = new sf::Font();
if(!m_pHeaderFont->LoadFromFile("data/LiberationSerif-Regular.ttf", 80))
    LOG_ERROR("Error loading font.");

// and later on this
creditsHeader.SetFont(*m_pHeaderFont);
creditsHeader.SetText("Credits");
creditsHeader.SetSize(80);

Is there any other solution for this?

Upgrade to SFML2. Its a branch in development but all the bugfixes and improvements makes it worth it.
