mx1:/home/moya/bind9# file /usr/lib/libdns.so.43.0.1
/usr/lib/libdns.so.43.0.1: ELF 32-bit LSB shared object, Intel 80386,
version 1 (SYSV), dynamically linked, stripped
First lines after debuild:
dpkg-buildpackage: set CFLAGS to default value: -g -O0
dpkg-buildpackage: set CPPFLAGS to default value:
dpkg-buildpackage: set LDFLAGS to default value:
dpkg-buildpackage: set FFLAGS to default value: -g -O0
dpkg-buildpackage: set CXXFLAGS to default value: -g -O0
I commented out the dh_strip line and rebuilt the package, this is the
backtrace now
