osc build --noservice --vm-type=kvm -j1

sometimes, but not always fails like this:

[  756s] broken payload ..................................................: ok
[  756s] connection lost: one attempt ....................................: ok
[  757s] connection lost: two attempts ...................................: ok
[  757s] connection lost: three attempts .................................: ok
[  758s] connection lost: manual retry ...................................: ok
[  758s] connection lost after 100-continue ..............................: ok
[  758s] test-http-client-errors.c:1319: Assert failed: resp->status == 200
[  758s] /bin/sh: line 1: 32065 Segmentation fault      ./$bin
[  758s] make[3]: *** [Makefile:1143: check-local] Error 1
