Request.setField crashes in SFML V2.0 OSX 10.6.8

[apollon0815]

Hello,

When code reaches Request.setField this error occurs:

malloc: *** error for object 0x7fff70431500: pointer being freed was not allocated.

Same thing in xcode 4.2. with attached code. Programm received signal: "SIGABRT" in 0x0000000100170b98

Regards
Mike

How did you get SFML ? Did you compile it yourself ? If yes, did you manage to fix issue 5 as explained on github ?

[apollon0815]

Hello,

It is the RC.

Last time I used C++ in a serious projekt is 10 years ago. So my knowledge is rusty and I would prefer to avoid compiling sfml myself.

Is Issue 5 the same error?

regards
Mike

[Hiura]

If you downloaded the RC then issue 5 should not be a problem (your problem looks like this issue but it's probably something else).

Could you give us the stacktrace of your application when the error occurs ?

[apollon0815]

Hope this is a stacktrace. ;-)
