Bug#656659: info not showing anything with certain build flags
Hi Karl, hi everyone,
on Debian we recently enabled hardening build flags, but that led to
a strange effect, namely that info didn't display *anything* at all.
You could start info, but there was an empty main window (text console),
but the status line showed the
----INfo: (dir)Top, 1 lines --All----------------------
and the lasst line showed
Welcome to Info version 4.13. Type h for help, m for menu item.
Typing m<TAB> also showed many entries, and I could browse some
info files. So for example
m basename
showed the coreutils.info file 18.1 'basename' ... and that was visible.
But doing
u u u u
to go to the Top dir file again showed nothing.
After removing the hardening flags it worked again, so I assume that is
is related to that. The way we are compiling is wiht
CFLAGS="-g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security -Wall"
CPPFLAGS="-D_FORTIFY_SOURCE=2"
CXXFLAGS="-g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security"
FFLAGS="-g -O2"
LDFLAGS="-Wl,-z,relro"
Does anyone have an idea why this might happen?
(I tried compiling current sources, but that didn't work out, configure
errors etc)
Best wishes
Norbert
