All callers of malloc should already do error checking, and may even be able to continue without the alloc succeeding. Moreover, common/malloc_simple.c is the only user of .rodata.str1.1 in common/built-in.o when building the SPL, triggering this gcc bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54303 Causing .rodata to grow with e.g. 0xc21 bytes, nullifying all benefits of using malloc_simple in the first place.
