The problem might be the newly introduced -r option, which is now passed on
by SDCC to gplink to circumvent problems with devices with all memory
locations being in shared banks; probably gplink now allocates r0xB0 to
the (shared) location 0x90, which it should not... You might try to compile
and link manually without -r to gplink.
Also check if you ran out of memory (consult the .map file, gplink -m).
HTH,
