Description

Captures build path, e.g., /build/1st/foo-42.0 v. /build/foo-42.0/2nd
.
Until early 2024 we varied the build path when testing packages from unstable
and experimental, which we have stopped doing now as the build path is recorded
as part of the environment and thus can be used when rebuilding.
.
This issue is kept here for the time being.
.
dpkg-buildflags version 1.20.6+ sets -ffile-prefix-map by default
(and -fdebug-prefix-map in older versions) which fixes this issue
in many cases, but not all (see: records_build_flags).
.
There are patches submitted upstream to address this specific issue, but they
are unlikely to be merged at this point:
.
https://gcc.gnu.org/ml/gcc-patches/2017-04/msg00513.html
.
When this is accepted into GCC upstream, we could remove this note.
In the meantime, please do not remove this issue, nor mark it as deterministic,
nor untag these packages.

Comments:

This library adds timestamps inside function methods.
When the example files are generated the current time is saved.
Command to find where are set the timestamps: ack-grep -B3 snprintf.*ptr

Our notes about issues affecting packages are stored in notes.git and are targeted at packages in Debian in 'unstable/amd64' (unless they say otherwise).
