libpthread: pthread_exit in static app. segfaults
Static applications that call pthread_exit on the main thread segfault. This is because after a thread terminates __uClibc_main decrements __nptl_nthreads which is only defined in pthread_create. Therefore the right solution is to add a requirement to pthread_create from pthread_exit. This patch has been backported from glibc tree: http://sourceware.org/git/?p=glibc.git;a=commitdiff;h=e1f0b2cfa14b058ab033431b70428ccda8ec6ed0 For further detail see also glibc bug at: http://sourceware.org/bugzilla/show_bug.cgi?id=12310 Signed-off-by: Filippo Arcidiacono <filippo.arcidiacono@st.com> Cc: Vladimir Nikulichev <v.nikulichev@gmail.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
