Core dump only on Solatris 8 not 9

[The Ha]

Hi
Thanks for bogofilter, it works great.
However, It works only on Solaris 9 SPARC server.
I also have 2 Solaris 8 Sun sparc servers that bogofilter
fail with a core dump.
Notes:  I have no problem building both 0.95.2 and 0.9.6 on these servers.
Both fail with core dump.

Here is few last line from my truss
..............................................
read(0, " F r o m   M A I L E R -".., 8192)     = 8192
brk(0x0007B9A8)                                 = 0

    Received signal #10, SIGBUS [default]
      siginfo: SIGBUS BUS_ADRALN addr=0xFFFFFFFF

Any idea how to fix this?
Thanks
