The problem is that Emacs is not determining the start of the data
segment properly on MIPS machines. In src/m/mips.h, we define
DATA_START as 0x10000000. There must be a reason for this, but it's
wrong on the machine you provided for testing; there, __morecore reports
the memory break (which must lie inside the data segment) as a value
less than 0x10000000.
If I comment out DATA_START, so that Emacs uses another method to
determine the start of the data segment size, everything seems to work
OK. But I don't know if this may lead to a different bug elsewhere.
