Opening the unused port & system call open("/dev/tty", ...) writev(7, [{"*** glibc detected *** ", 23} -

I have a Linux platform (3.12.13 and 2.6.35.3), & amp; Imx5x series processor In my program I am using two serial ports to read / dev / ttymxc2 & amp; / Dev / ttymxc1 After some period executes / dev / tty open system calls which is not part of my program & amp; The error is open ("/ dev / tty", ...) writev (7, [{" * glibc detected * ", 23}.

suggest port that I'm not used in your code, still / dev / tty / call systems perform to open.

the log some ladders.

Please suggest some solution

You have to fix a heap corruption bug that glibc was searched for you.

One way to do this is to run your program under Wolfrand, but I believe it is not available for imx5x .

Another way is to run the program with the export MALLOC_CHECK_ = 2 . See.

Still have to use another method (if your toolchain supports it).
