First I observed that lt-query-test runs forever (up to 16 hours, once, using as much CPU as it can get), and when killed -9, the system stopped responding. I once observer lt-server-auth-test starting curl before it hung the system. Failure occurs with both -O2 and -O0 in C*FLAGS. elmer /mnt/alt/portage-tmp/portage/net-libs/libsoup-2.4.1/work/libsoup-2.4.1/tes ts # ./query-test query-test: OK * elmer

I'll try FEATURES=userpriv next.
Ouch, even a mere user can trigger the hang.
The problem seems to have gone away with newer kernel versions. Marking as fixed accordingly. I hope to one day report back with the reason this was happening, and what fix in the kernel fixed this issue as well.
