Hi,
I would like to report a segfault when using the python ctypes
bindings to list properties.
Trying to summarize the situation:
- Having the most frequent problem with
RemoteRepository.proplist(path, rev).
- The crash happens randomly in libapr or libc. It is not happening
consistently when reading a certain path/revision.
- Crashes significantly more frequently when accessing repo via
file:// compared to http://.
- System: OpenSuse 11.1 x86_64, Svn 1.5.7 from package management
(Yast) and csvn binding built by me.
- Tried both python 2.6 from Yast and 2.6.2.
- Tried updating to Svn 1.6.3 (from OpenSuse build service)
Same python code tested successfully on Mac OS with Svn 1.6.x from
MacPorts.
See below:
- Excerpt of segfaults in messages log.
- Stacktrace produced with gdb.
I would like some input on how to report this issue. Can anyone
isolate the issue to a specific module by looking at the below
information? I can't say whether the issue is with ctypes-bindings,
ctypesgen, python, Svn core, libapr or libc or something specific to
OpenSuse.
Thanks in advance,
Thomas Åkesson
