+# This test is to demostrate the issue:
+#
+# hidden symbol '__cxa_begin_cleanup' in ./obj/local/armeabi/libgnustl_static.a(eh_arm.o)
+# is referenced by DSO ./obj/local/armeabi/libidiv.so
+# hidden symbol '__cxa_type_match' in ./obj/local/armeabi/libgnustl_static.a(eh_arm.o)
+# is referenced by DSO ./obj/local/armeabi/libidiv.so
+#
+# File idiv.cpp contains code potentially causes divide-by-zero exception. libidiv.so
+# is built with libgnustl_static.a which provides __cxa_begin_cleanup and
+# __cxa_type_match needed by unwinder in libgcc.a. Unfortunately both are built
+# with hidden visibility, and causes warnings as the above when libidiv.so is used
+# to link other binaries.
+#
+# The fix is to unhide both __cxa_begin_cleanup and __cxa_type_match
