You get this if glibc and GCC have mismatched stack checking 
configuration.  To avoid that, use the --with-glibc-version=<major.minor> 
option when configuring a bootstrap GCC to be used to build glibc.

Mainline glibc's build-many-glibcs.py knows how to configure GCC and glibc 
for building many different configurations.  It uses 
--disable-libsanitizer, but if libsanitizer is meant to work for all glibc 
configurations you could try removing it (adding it back for the initial 
bootstrap GCC only) and seeing what libsanitizer problems it shows up.
