valgrind Conditional jump or move depends on uninitialised value(s)
Hi,

Im confused about where to look for the error in my code since there is no information about the line number.
Can anybody help?

It means an if() tests a variable - but the variable was never initialized.

Yes, but my code is pretty long, thats why i didnt post it. So i have many "if"s there.
Valgrind is usually writing the line number of the code in which the problem occurs. But that is not the case here and thats what is confusing me.
