Negative Array Size Exception #2193

Closed Shridharfly closed 7 years ago

Shridharfly commented 7 years ago

I am using z1 motes and simple rpl-udp client and server in contiki 3.0, cooja simulator. The OS and JVM are both 32-bit type.

I am just trying to test quark using motes. When I run code using simple terminal, without motes and cooja simulator, it works fine. But if I test it using motes it reports following error:

How do I get rid of this error?

Trying to use malloc() in contiki caused the error.
