g++ and pthreads also causes issues: https://stackoverflow.com/questions/35116327/when-g-static-link-pthread-cause-segmentation-fault-why

+
+
+

As a consequence, the following fails:

+
+
+
+
./run --userland userland/cpp/atomic.cpp --static
+
+
+
+

with error:

+
+
+
+
qemu-x86_64: /path/to/linux-kernel-module-cheat/submodules/qemu/accel/tcg/cpu-exec.c:700: cpu_exec: Assertion `!have_mmap_lock()' failed.
+qemu-x86_64: /path/to/linux-kernel-module-cheat/submodules/qemu/accel/tcg/cpu-exec.c:700: cpu_exec: Assertion `!have_mmap_lock()' failed.
+
+
+
+

and if we manually build and run natively on host it segfaults.

+
+
+

If we hack the compilation command to do instead:

+
+
+
+
-pthread -Wl,--whole-archive -lpthread -Wl,--no-whole-archive
+
+
+
+

then it works. We should automate that at some point.
