commit 758ecf7fe1cb15abb87c796fb3a7f15933c56f67 Author: Guillem Jover <[email protected]> Date: Sat Aug 27 22:32:55 2016 +0200 build: Fix the __progname check to avoid the optimizer discarding the symbol Because we were assigning to another unused variable, when building the check with optimizations enabled, which is the default when using gcc as the compiler, the variable was being discarded. Instead pass it to printf() so that it cannot do so. --- debian/changelog | 1 + m4/dpkg-funcs.m4 | 5 ++--- 2 files changed, 3 insertions(+), 3 deletions(-) diff --git a/debian/changelog b/debian/changelog index 53ea959..4001219 100644 --- a/debian/changelog +++ b/debian/changelog @@ -4,6 +4,7 @@ dpkg (1.18.11) UNRELEASED; urgency=medium * Build system: - Add support for profiling perl modules. - Clean up compiler and linker automatic flag usage in configure. + - Fix the __progname check to avoid the optimizer discarding the symbol.
