Subject: bdr: fix: use palloc0() instead of palloc()
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=baadc63e70eeaff98147e3263129df3c83785e07;p=users%2Fandresfreund%2Fpostgres.git

bdr: fix: use palloc0() instead of palloc()

When using palloc(), bdr_startup_context->workers is not NULL/NIL and
therefore the later lcons() call will lead to a segfault.
