-Wl,-Bsymbolic-functions in Ubuntu but not debian/ why?


does anybody recall why Ubuntu has -Wl,-Bsymbolic-functions in
dpkg-buildflags --get LDFLAGS but not Debian? It seems to be the case for
about 10 years now, according to dpkg's changelog.

I came across this change because of a delta we have been carrying in the
autofs package for fix segfaults on startup and other issues: Not working
properly with compile options "-symbolic-functions" autofs start
fails: segfault at 0 ip ...

d/rules has had a trick to drop -Bsymbolic-functions from LDFLAGS at build
time (hello sed), but it still leaks through when building the lookup_ldap
module via $(krb5-config --libs), hence the current
d/p/fix-lookup-ldap-crash.patch patch we have been carrying.

Debian doesn't set -Bsymbolic-functions, and upstream works if you just
make && make install it, that's why I guess the patch was never forwarded
up the chain.
