For cm3, that has the same basic architecture, I exchanged
 cm3/os/context: Push direct to PC register instead of push to lr and branch lr.
 @@ -114,7 +114,7 @@ static void NutThreadEntry(void) __attribute__ ((naked));
 void NutThreadEntry(void)
 {
     /* Load argument in r0 and jump to thread entry. */
-    asm volatile ("ldmfd   sp!, {r0, lr}\n\tbx lr":::"r0", "lr");
+    asm volatile ("pop {r0, pc}\n\t":::"r0", "pc");
 }

Could you perhaps try to do the same for arch/arm/os/context.c.
Obvious both versions compile for me, to the test must be done with your
compiler.

Thanks
