[jira] [Closed] (SVN-3398) Segmentation fault when accessing BDB repositories with enabled run-time module search
[ https://issues.apache.org/jira/browse/SVN-3398?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Daniel Sahlberg closed SVN-3398.
--------------------------------
Resolution: Won't Fix
BDB is deprecated since Subversion 1.8 (which is EOL a long time ago). Closing this as won't fix as discussed on dev@ https://lists.apache.org/thread/2w1o5dzqbpbg5rjbbwltcnf7m535zmg2

> Key: SVN-3398
> URL: https://issues.apache.org/jira/browse/SVN-3398
> Project: Subversion
> Issue Type: Bug
> Components: libsvn_fs_base
> Affects Versions: 1.6.x
> Reporter: Arfrever Frehtes Taifersar Arahesis

> {noformat:nopanel=true}
> When Subversion is configured with the '--enable-runtime-module-search' option,
> then segmentation faults occur during some operations when BDB repositories are
> accessed. This problem might be related to pool lifetime. This problem exists
> at least in Subversion 1.5.*, 1.6.* and trunk.
