988+# These are generic cover-alls which catch a lot of stuff
989+# in various combinations of ld, libc and libpthread
990+#
991+# Note this is heavyhanded and not very clever:
992+#
993+# - suppress anything that has its top frame in ld.so
994+# That's fine, since it's mostly dynamic linking stuff,
995+# which has various deliberate (harmless) races
996+#
997+# - suppress anything that has its top frame in libc.so.
998+# This really isn't clever, since it could hide some
999+# legitimate races. But the problem is, if we don't do
1000+# this, then loads of errors to do with stdio are reported, because
1001+# H fails to see glibc's internal locking/unlocking of FILE*s
1002+# as required by POSIX. A better solution is needed.
