JN5168: memcmp does not work under Beyond Studio.

memcmp does not work properly.

If I call memcmp with a length > 1 on identical memory areas it returns a non-zero value.

I've tried this on the application template (AN-1174) end device as follows

vInitSystem();

memset(b,0,sizeof(b));

memset(c,0,sizeof(c));

b[0]=1;

b[18]=18;

c[0]=1;

c[18]=18;

if (memcmp(b,c,2)!=0) for (;;);

vStartActiveScan();

It does not connect. If I change the compare length to 1 it does connect.

If I change the BA toolchain path in config_ba2.mk to "ba-elf-ba2-r34135" it works.

If I force it to use the optimised versions under r36379 it works.

I am using Beyond Studio Build 1308 and JN-SW-4143 Build 1307.

Any ideas?
