Usage of Balloc in Newlib


Hello,

the Balloc() function can return NULL in case _calloc_r() returns NULL. All users of Balloc() in Newlib don't check for a NULL pointer. Is this Balloc() supposed to never fail?

./libc/stdlib/strtod.c: bd = Balloc(ptr,bd0->_k);
./libc/stdlib/strtod.c- Bcopy(bd, bd0);
