Hi All,

After the import of libz 1.1.4, rpm (from ports) dumps core when
trying to install linux_base.

# make install
===>  Installing for linux_base-6.1_1
setup-2.0.5-1.noarch.rpm
filesystem-1.3.5-1.noarch.rpm
basesystem-6.0-4.noarch.rpm
ldconfig-1.9.5-15.i386.rpm
Segmentation fault - core dumped
*** Error code 139

Stop in /usr/ports/emulators/linux_base.
*** Error code 1


When runing rpm inside gdb, SEGV seems to be happing inside libz.

Starting program: /usr/local/bin/rpm -U --ignoreos --root /compat/linux --dbpath /var/lib/rpm --nodeps --replacepkgs --noscripts /usr/ports/distfiles/rpm/ldconfig-1.9.5-15.i386.rpm

Program received signal SIGSEGV, Segmentation fault.
0x80a42b3 in inflate_codes ()
(gdb) where
#0  0x80a42b3 in inflate_codes ()
#1  0x80a1d13 in inflate_blocks ()
#2  0x809f737 in inflate ()
#3  0x809ea94 in gzread ()
#4  0x808184f in gzdRead (cookie=0x813a900, 
    buf=0x81453f0 ' <repeats 200 times>..., count=14) at rpmio.c:2230


I then went into src/lib/libz and checked the difference between libz 1.1.4
and older 1.1.3. I found that if I backout the change for infcodes.c 1.3,
rpm does not dump core.

Could someone take a look into this?

Thanks,
  Haro
