Apache Segmentation fault
Hello,
I'm trying to migrate my svn repository to a new (SuSE 9.0) server. I
have svn 1.3.2 running just fine on my old SuSE 8.2 server, with Apache
2.0.48. But on my new server (same Apache version), I can't get the
Python http bindings to work. Whenever I access the repository through
http, I get a seg fault:

--------------------------------------------------
Does anybody have any idea what could be wrong ? I already spent hours
recompiling, searching the mailing list and so on, but to no avail.
I compiled svn with the following options:
$ ./configure --enable-dav --enable-so --with-ssl --prefix=/usr
--mandir=/usr/share/man --with-apxs=/usr/sbin/apxs2 --with-apr=/usr/bin
--with-apr-util=/usr/bin
I also tried:
$ ./configure --enable-dav --enable-so --with-ssl --prefix=/usr
--mandir=/usr/share/man --with-apxs=/usr/sbin/apxs2 --with-apr=/usr/bin
--with-apr-util=/usr/bin CFLAGS=-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64
And my repository is file based, not Berkeley-DB.
Regards,
Daniel

Sorry, I was accidentally talking about Python because I'm using
ViewCVS, written in Python.
The problem, of course, is in the svn Apache module. I get the seg-fault
whenever I try to access the subversion server with the http(s)
protocol. I don't have a problem when using the file:// protocol.

"Python http bindings"? What exactly do you mean by that? Are you
running through a Python-based client? You've shown a server-side
debugging transcript below, but not the client actions...
I don't have any clue off the top of my head what's causing that
null-pointer dereferencing ("r=0x0"), sorry.
