tests/gnrc_tcp_*: not working on 6Lo-based boards #10947
Description
Description
Both test applications tests/gnrc_tcp_server and tests/gnrc_tcp_client do not work on current master using boards (I tried with samr21-xpro and iotlab-m3). It used to work on 2018.07 release branch though.
Steps to reproduce the issue
Build/flash/term one of the aforementioned applications to a board and wait for the serial output.
Expected results
The respective application should print some status information, among others IPv6 address, port, ...
Actual results
You see nothing because the board sees to hard fault before main() is reached. By enabling ENABLE_DEBUG in auto_init you can see at least some output before the board crashes.
