cat > test.c <<EOF

void *test() { return current_thd; }
EOF

gcc -ftls-model=3Dinitial-exec -shared -fPIC -o libtest.so test.c

undefined symbol: current_thd   (./libtest.so)
Segmentation fault

This failure is particularly annoying since the above tracing command is us=
ed
when building RPM packages.
