+qemu-user-static for armhf: segfault in threaded code
+
+
+Currently running QEMU from git (fedf2de31023) and running the armhf version of qemu-user-static which I have renamed qemu-armhf-static to follow the naming convention used in Debian.
+
+The host systems is a Debian testing x86_64-linux and I have an Debian testing armhf chroot which I invoke using schroot.
+
+Majority of program in the armhf chroot run fine, but I'm getting qemu segfaults in multi-threaded programs.
+
+As an example, I've grabbed the threads demo program here:
+
+    https://computing.llnl.gov/tutorials/pthreads/samples/dotprod_mutex.c
+
+and changed NUMTHRDS from 4 to 10. I compile it as (same compile command on both x86_64 host and armhf guest):
+
+    gcc -Wall -lpthread dotprod_mutex.c -o dotprod_mutex
+
+When compiled for x86_64 host it runs perfectly and even under Valgrind displays no errors whatsoever.
+
+However, when I compile the program in my armhs chroot and run it it usually (but not always) segaults or hangs or crashes. Example output:
+
+
+    (armhf) $ ./dotprod_mutex
+    Thread 1 did 100000 to 200000:  mysum=100000.000000 global sum=100000.000000
+    Thread 0 did 0 to 100000:  mysum=100000.000000 global sum=200000.000000
