Hello Guix!
I have question about reproducible builds and generating debugging
information.
As I was tracing curl code, I needed to rebuild the package with
"-ggdb" in CFLAGS and enable debug among outputs.
The later doesn't change the hash (and the generated code), but the
first does. So I'd like to propose to put "-ggdb" to generally applied
CFLAGS for whole distribution. I don't know if it will cause any
performance penalty, but it would be possible to not only have
reproducible builds but also inspect them and debug them...
Without it it can be hard to analyze core dumps and trace.
WDYT?
