git-svn crashing perl

git-svn crashing perl

[Alex Bennee]

Hi,

Doing a git-sv fetch --fetch-all is generating a SEGV in perl while I
try and update my repo. Although I can look at the backtrace in perl
it doesn't really tell me much. Any tips on how I can get more info?

This seems to be a problem of the subversion perl bindings. See for example:

Looks similar. libapr certainly seems to be breaking something:


Core was generated by `/usr/bin/perl

I found another bug report that seems to be related
http://bugs.gentoo.org/show_bug.cgi?id=223747

There is a workaround mentioned: disable runtime-module-search when
building subversion.
