I'm not sure when did this issue arise, perhaps after a update of my glibc
or whatever packages that I could not remember,  but seems ok with root
somehow, anyway, I used strace to track the running process and get the
following message ( the last few lines):

...
open("/lib/libgcc_s.so.1", O_RDONLY)    = 4
read(4, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\200\25"..., 512) =
512
fstat64(4, {st_mode=S_IFREG|0644, st_size=168291, ...}) = 0
mmap2(NULL, 34052, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 4, 0) =

mmap2(0xb684c000, 4096, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 4, 0x7) = 0xb684c000
close(4)                                = 0
gettimeofday({1151073643, 460980}, NULL) = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
exit_group(1)                           = ?

I'm sure that's not related with permissions, but no idea about how this
would happen.
hope the strace output for the root may help:

 write(3, "\31\0\v\0\3\0`\2\0\0\0\0! Y\267\3\0`\0021\2\0\0000\2\0"..., 48) =

read(3, "\1\2\273\0\0\0\0\0\5\0\200\1\0\0\0\0\0\0\0\0\37\0\0\0\320"..., 32)
= 32
gettimeofday({1151073832, 21086}, NULL) = 0
gettimeofday({1151073832, 21215}, NULL) = 0
poll([{fd=3, events=POLLIN, revents=POLLIN}], 1, 0) = 1
ioctl(3, FIONREAD, [64])                = 0
read(3, "\34\0\273\0\3\0\240\0020\2\0\0\240\345j\0\1\0\0\0\0\0\0"..., 64) =

write(3, "\20\0\n\0\37\0`\2_ADOBE_ACROBAT_OPEN_FILE"..., 40) = 40
read(3, "\1\0\274\0\0\0\0\0002\2\0\0\0\0\0\0\1\0\0\0\37\0\0\0\320"..., 32) =
32
exit_group(0)                           = ?

thanks in advance..

Hmm, acroread doesn't link directly against libgcc_s.so.  However, it
will pay attention to your ~/.gtkrc-2.0 file, and possibly attempt to
load an engine to blend with a KDE environment.  For example, I get:

12021 open("/usr/lib/gconv/ISO8859-1.so", O_RDONLY) = 6
12021 open("/home/rjf/.gtkrc-2.0", O_RDONLY|O_LARGEFILE) = 6
12021 open("/usr/share/themes/Qt/gtk-2.0/gtkrc", O_RDONLY|O_LARGEFILE) = 7
12021 open("/usr/lib/gtk-2.0/2.4.0/engines/libqtengine.so", O_RDONLY) = 8
12021 open("/usr/qt/3/lib/libqt-mt.so.3", O_RDONLY) = 8
12021 open("/etc/ld.so.cache", O_RDONLY) = 8
12021 open("/usr/lib/gcc/i686-pc-linux-gnu/4.1.1/libstdc++.so.6", O_RDONLY) = 8
12021 open("/usr/lib/libmng.so.1", O_RDONLY) = 8
12021 open("/usr/lib/libjpeg.so.62", O_RDONLY) = 8
12021 open("/usr/lib/libpng.so.3", O_RDONLY) = 8
12021 open("/usr/lib/libXft.so.2", O_RDONLY) = 8
12021 open("/usr/lib/libSM.so.6", O_RDONLY) = 8
12021 open("/usr/lib/libICE.so.6", O_RDONLY) = 8
12021 open("/lib/libgcc_s.so.1", O_RDONLY) = 8

Does it still fail if you "mv ~/.gtkrc-2.0 ~/._gtkrc-2.0"?

Have you tried a revdep-rebuild?  Did you recently change gcc
versions?  Do you use prelinking, and if so, have you done a "prelink
-aq"?

yes, it failed as always. I've fould the problem has nothing to do with
gtkrc-2.0,

Have you tried a revdep-rebuild?  Did you recently change gcc
> versions?  Do you use prelinking, and if so, have you done a "prelink

I don't use prelink.. , and even don't know what it is....
I compared all the open() system calls between outputs generated by root and
the normal user, and found something strange:  both root and the normal user
version trying to open libstdc++.so.6, after checking /etc/ld.so.conf, what
have made me confused is the root
version choose /usr/lib/libstdc++-v3/ thus the normal user choose
/usr/lib/gcc/i686-pc-linux-gnu/4.3.6/, probably this is the answer to the
crash, but I just wonder what make them having different choices with the
same ld.so.conf?


thank you..

The user environment can override ld.so.conf.  Try "env | grep LD" as
both the normal user and root.

mm, I have totally forgotten those tricks, will check it back home.
thanks a lot Richard..

still the question is how could this happen? no special environment
variables, if the acroread has been compiled with version 5, it should be
failed even for the root, just odd.
