I experience this heavily on Debian Jessie with

git-svn 1:2.1.4-2.1+deb8u2
libsvn-perl 1.8.10-6+deb8u4

to point where git-svn unusable.

The error was the same
error: git-svn died of signal 11
(no other information printed)

I try several month ago on Arch linux virtual machine guest on Debian Jessie host and had same, signal 11.

Some people have similar on Ubuntu:

Hi, this is possibly related to #780246
https://bugs.debian.org/780246
https://public-inbox.org/git/0BCA1E695085C645B9CD...@GBWGCEUHUBD0101.rbsres07.net/T/

In any case, can you get a backtrace to confirm if you see the
same thing in the other reports? Thanks.
