# Suppression patterns for libc.

# Suppress all data races where the topmost frame is inside libc.so. Although
# this could hide some real data races, unfortunately this is the only way to
# not report any false positives on stdio functions. The glibc functions
# manipulating FILE objects use locking primitives that cannot be intercepted
# easily. See also the definitions of _IO_lock_lock() etc. in the file
# nptl/sysdeps/pthread/bits/stdio-lock.h in the glibc source tree.

# Suppression patterns for libstdc++, the implementation of the standard C++
# library included with the gcc compiler.

# Note: several versions of the libstdc++ library (4.2.2, 4.3.2, 4.4.0, 4.5.0
# and their predecessors) contain an implementation of the std::string class
# that triggers conflicting memory accesses. See also
