INN with large file support dumps core under Solaris 2.7

[Joe St Sauver]

Had a mysterious experience whereby today's snapshot would mysteriously
die with nothing to the syslog; trussing innd -d -f resulted in output
that looked like

....
brk(0x002E7000)                                 = 0
ioctl(6, TCGETA, 0xDFFFF784)                    Err#25 ENOTTY
read(6, " # #     $ R e v i s i o".., 8192)     = 325
read(6, 0x002D900C, 8192)                       = 0
llseek(6, 0, SEEK_SET)                          = 0
read(6, " # #     $ R e v i s i o".., 8192)     = 325
read(6, 0x002D900C, 8192)                       = 0
llseek(6, 0, SEEK_CUR)                          = 325
close(6)                                        = 0
open64("/dev/null", O_RDONLY)                   = 6

fcntl(16, F_SETFD, 0x00000001)                  = 0
fstat64(16, 0xDFFFF940)                         = 0
mmap64(0x00000000, 1186451, PROT_READ|PROT_WRITE, MAP_SHARED, 16, 0) = 0xDF1C0000

brk(0x0093D800)                                 = 0
open64("/news/etc/newsfeeds", O_RDONLY)         = 17
fstat64(17, 0xDFFFF940)                         = 0
read(17, " M E / n e w s . c g o c".., 3751)    = 3751
close(17)                                       = 0
    Incurred fault #6, FLTBOUNDS  %pc = 0x0005981C
      siginfo: SIGSEGV SEGV_MAPERR addr=0xE640D77C
    Received signal #11, SIGSEGV [default]
      siginfo: SIGSEGV SEGV_MAPERR addr=0xE640D77C
        *** process killed ***

Now obviously that's an odd argument to the read(17, ... call, but I am equally
suspicious of the mmap'd files based on past experience with inadequately 
sized mmap'd regions. This is with inn-2000-02-25_03-01 under Solaris 2.7
on sun4d (SPARC) architecture built using

./configure         --prefix=/news \
                    --bindir=/news/bin \
                    --mandir=/usr/local/man \
                    --with-perl \
                    --with-db-dir=/news \
                    --with-spool-dir=/var/spool/news \
                    --with-log-dir=/var/log/news \
                    --with-tmp-path=/news/tmp \
                    --with-sendmail=/usr/lib/sendmail \
                    --with-largefiles --disable-enable-tagged-hash
