Subject svn 1.8 client segmentation fault when checking out Subversion trunk repository
Date Tue, 08 Oct 2013 18:35:59 GMT
Hi everyone,

I'm trying to compile svn 1.8.3 with lsbcc (Linux Standard Base).

Everything compiles fine but when trying to checkout Subversion trunk
( http://svn.apache.org/repos/asf/subversion/trunk/ )
the svn client crashes with the segmentation fault in the middle of checkout 
and I get broken working copy.

This is the GDB output with enabled debugging output --enable-maintainer-mode 
option:

-------

My guess is that it is related to libserf:
- svn 1.7 compiled with the same libraries and configure options works properly
- the only difference between svn 1.7 and svn 1.8 in my environment is the http 
library serf that is used by svn 1.8.


Has anybody seen a similar issue or any idea what am I doing wrong when 
compiling svn 1.8?


Thanks,
Martin Zibricky
