I think it should be a printf() function.

Your error is for the in printf() function.
___LINE___ isn't a C style string, its an integral type (the exact flavor escapes me at the moment). %s is the wrong format. This is why, in C++, it is recommended that you avoid printf() and friends, and use iostreams instead.

%s is used for print string.

example= printf("%s", "_LINE_");

or char *p = "_LINE_" ;

Dheerandra: it may not work as __LINE__ prints the line number, so the intention here is different.

How can we debug the segmentation fault in a program which has been compiled without "-g" option?
