peripheral and central UART sample crash when sending longer messages

[PingISTL]

Hello, All

I received following message when I test the code, it appears on both sides, 

ASSERTION FAIL [chunk_used(h, c)] @ WEST_TOPDIR/zephyr/lib/os/heap.c
:163

unexpected heap state (double-free?) for memory at 0x20006fec

And then it reset, what is the problem please?

I have not changed any code for both.

Thank you !

Hi,

We now have a pull request up with a fix for the double free issue in these samples.
