Re: previous bug report about gdb using significantly more memory than
    gdb3.4.

After a debug session on gdb 3.5 I discovered that the problem appears
to be in the malloc.c provided with gdb.

When reading my executable's symbol table, malloc is called 841 times
to request 4088 bytes.  After every one of these 4088 byte malloc calls,
the data segment size goes up by 8192 bytes.  As a result, gdb uses
an extra 3.5 Megabytes of data space.  Linking in the system malloc.o
instead seems to fix the problem.  Looking back, I see that I used the
system malloc on gdb3.4 as well.
