Yes, this seems different from the EPIPE bug, alas.

I get a core dump (for some small process, I don’t know what: 1048576 bytes. Died of signal 5 in pthread_mutex_unlock) and git-svn is still going.

 $ git svn clone -s https://gate.svn.sourceforge.net/svnroot/gate
 Initialized empty Git repository in /tmp/gate/.git/

Sitting there quietly.  ltrace tells me it’s busy copying around data.
