I believe bug is here:
_memcpy:
/* Determine copy direction */
cmp r1, r0
bcc .Lmemcpy_backwards
IT(tt, eq)
moveq r0, #0 /* Quick abort for len=0 */
#if defined(__USE_BX__)
bxeq lr
#else
moveq pc, lr
#endif
Does removing just one instruction "moveq r0, #0" help?
If not, you probably need to replace it with "moveq r0, r1"
