Bug#347878: libmysqlclient15 calls into libmysqlclient12, leading to apache2 segfault

The thing that us (e.g. Steve, Sean and me) interests far more is *why* this bug it happening at all because it shows the exact symptoms of a situation we were working hardly to prevent and which luckily did not show up with other packages so far. bye, -christian- -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Your md5sums and versions look but I still can't reproduce it.

Bug#347878: libmysqlclient15 calls into libmysqlclient12, leading to apache2 segfault
Hi again,
sorry for flooding this list again, but i've worked around the problem by
rebuilding libapache2-mod-auth-mysql against libmysqlclient15 so
it-works-for-me now.
2 problems occured during "dpkg-buildpackage -uc -us -rfakeroot" (that's
how i compiled the package):
- it depended on apache-dev, although it build for apache2-dev too and i
really did "apt-get source libapache2-mod-auth-mysql" before.
- although debian/rules is giving "--enable-apache2" to ./configure, it
looked
for apxs and not apxs2. forcing via "--disable-apache13" does help.
it seems that --enable-apache2 did not unselect $buildapache13, because
this option is set to "yes" by default:
checking for mysql_init in -lmysqlclient... yes
DEBUG: "${enable_apache13+set}"
DEBUG: "${enable_apache2+set}" set
DEBUG: "${with_apxs+set}"
DEBUG: "x$buildapache13" xyes
DEBUG: x$buildapache2" xyes
configure: error: Apache extension helper apxs not found!
a simple patch[0] shows it all. strange though, that nobody could
reproduce #347878 :\
thanks,
Christian.

Bug#347642: Bug#347878: libmysqlclient15 calls into libmysqlclient12, leading to apache2 segfault
hi all[0] i've debugged the issue a bit further and it seems that not apache2 nor libmysqlclient15 is to blame, but libmysqlclient12 :) normally i have apache2 started and both libaries are used: [EMAIL PROTECTED]:~# apache2 /usr/lib/libmysqlclient.so.12.0.0 apache2 /usr/lib/libmysqlclient.so.15.0.0 libmysqlclient.so.12 is loaded, because i'm using mod_auth_mysql too and its module is linked against libmysqlclient.so.12: % ldd /usr/lib/apache2/modules/mod_auth_mysql.so linux-gate.so.1 => (0xe000) libmysqlclient.so.12 => /usr/lib/libmysqlclient.so.12 (0xb7f65000) libc.so.6 => /lib/tls/libc.so.6 (0xb7e2e000) libz.so.1 => /usr/lib/libz.so.1 (0xb7e1a000) libcrypt.so.1 => /lib/tls/libcrypt.so.1 (0xb7dec000) libnsl.so.1 => /lib/tls/libnsl.so.1 (0xb7dd6000) libm.so.6 => /lib/tls/libm.so.6 (0xb7db) /lib/ld-linux.so.2 (0x8000) so when i disable mod_auth_mysql (from debian's libapache2-mod-auth-mysql), apache2 won't segfault. my question is now: why does libmysqlclient.so.15 call libmysqlclient.so.12 at all? (as shown in the backtrace). because mod_auth_mysql works as expected: when accessing protected directories (username/passw prompt). the directory of the torrentflux installation is not even protected by mod-auth-mysql. and: should i set up another bugreport for libmysqlclient12? (i doubt that, though) i could provide shell access to my box if someone wants to play around a bit... thank you for your time, Christian. [0] if i should remove someone from the Cc next time, pls tell me so in private, so we don't spam the bugreport. -- make bzImage, not war -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Package: libmysqlclient15 Version: 5.0.18-3 Severity: important Hi, I have submitted #347642 regarding an apache segfault, but it turned out that apache2 is only segfaulting when libmysqlclient15 calls libmysqlclient12, but i don't know why. i have to keep both versions (along with libmysqlclient14) installed, as several other packages depend on them. here's a snippet of the backtrace, which is also included here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=347642 > Program received signal SIGSEGV, Segmentation fault. > [Switching to Thread -1215121184 (LWP 6378)] > 0xb79054cf in vio_in_addr () from /usr/lib/libmysqlclient.so.12 > (gdb) bt > #0 0xb79054cf in vio_in_addr () from /usr/lib/libmysqlclient.so.12 > #1 0xb77bad4a in mysql_real_connect () from > /usr/lib/libmysqlclient.so.15 if you need further information, please let me know. thank you for your time, Christian. -- System Information: Debian Release: testing/unstable APT prefers unstable APT policy: (990, 'unstable'), (500, 'testing') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.15 Locale: LANG=C, LC_CTYPE=C (charmap=ANSI_X3.4-1968) (ignored: LC_ALL set to C) Versions of packages libmysqlclient15 depends on: ii libc62.3.5-11 GNU C Library: Shared libraries an ii mysql-common 5.0.18-3 mysql database common files (e.g. ii zlib1g 1:1.2.3-9 compression library - runtime libmysqlclient15 recommends no packages. -- no debconf information (END) -- make bzImage, not war -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
