[Zlib-devel] bus error when using new Andler32 patch

[Vincenzo Innocente]

  Hi,
I applied the patches.
compiles and link fine
tests fails 
for instance

gdb ./example64
zlib version 1.2.5 = 0x1250, compile flags = 0xa9

Program received signal SIGBUS, Bus error.
0x00000033f8c7bebe in memcpy () from /lib64/libc.so.6
(gdb) where
#0  0x00000033f8c7bebe in memcpy () from /lib64/libc.so.6
#1  0x0000000000401d93 in fill_window ()
#2  0x0000000000402461 in deflate_slow ()
#3  0x0000000000403537 in deflate ()
#4  0x0000000000401b76 in compress ()
#5  0x0000000000400a99 in test_compress ()
#6  0x00000000004018bc in main ()

similar for 
minigzip64
both in compress and decompress mode

tryed with
gcc 4.5.1, on
Intel xeon-nehalem  L5520 
kernel 2.6.18-194.11.3 (RHL5)
and with
gcc 4.6 on
intel i7-2600K
kernel 2.6.32-71.14.1 (RHL5)

all x86_64 native

setting
-DNO_ADLER32_VEC
produces correct results as before the patch (al least)

Jan, do you have a test for just Adler32?

cheers,
   Vincenzo
