####################################################
# glibc-2.X specific
# These are generic cover-alls which catch a lot of stuff
# in various combinations of ld, libc and libpthread
#
# Note this is heavyhanded and not very clever:
#
# - suppress anything that has its top frame in ld.so
#   That's fine, since it's mostly dynamic linking stuff,
#   which has various deliberate (harmless) races
#
# - suppress anything that has its top frame in libc.so.
#   This really isn't clever, since it could hide some 
#   legitimate races.  But the problem is, if we don't do
#   this, then loads of errors to do with stdio are reported, because
#   H fails to see glibc's internal locking/unlocking of FILE*s
#   as required by POSIX.  A better solution is needed.
#
# - some of the stdio functions in newer glibc manipulate stdio
#   FILE*s state through mempcpy, which we intercept, so we also need
#   to suppress such manipulations.

# These are very ugly.  They are needed to suppress errors inside (eg)
# NPTL's pthread_cond_signal.  Why only one stack frame -- at least we
# should see the wrapper calling the real functions, right?
# Unfortunately, no: the real functions are handwritten assembly (in
# the glibc-2.5 sources) and does not create a proper stack frame.
# Therefore it's only one level of unwinding before we're back out in
# user code rather than the 2 levels you'd expect.
