[debhelper-devel] Bug#742701: package built without _FORTIFY_SOURCE=2, debhelper or schroot issue?

[Matthias Klose]

Package: debhelper,schroot
Severity: important

seen in unstable, according to
http://qa.debian.org/bls/packages/s/schroot.html
https://buildd.debian.org/status/fetch.php?pkg=schroot&arch=i386&ver=1.6.8-1&stamp=1388837978

  - schroot 1.6.8-1 sets debian/compat to 9
  - schroot sets DH_OPTIONS = --buildsystem=cmake

but CPPFLAGS are not appended to CFLAGS/CXXFLAGS as mentioned in #668813. 
exporting DH_OPTIONS doesn't help either.

if you're not overwriting things like in korundum, appending the CPPFLAGS seems 
to work. can't see what to fix in schroot.
