On gcc 4.8.4, boost 1.54, with commit 027aef5 built in RelWithDebInfo (and apex, if thats important), the following snippet shows a minimal example reproducing the segfault when gathering multiple times: https://gist.github.com/ltroska/080e7a41572c454a1a65 . I ran it with ./main -0 -l2 & ./main -1 --hpx:run-hpx-main . It does work when using one locality, i.e. calling ./main . The actual output is here: http://pastebin.com/GXegsJWe .
