Control: affects -1 + src:indent
[ Reason ]
This upload fixes Bug #1036851, where indent crashes with the following message
on a real file from the gstreamer project:
indent: Virtual memory exhausted.
free(): double free detected in tcache 2
[ Impact ]
Currently users of stable can't use indent with certain inputs,
as it crashes.
[ Tests ]
The upstream package has a test suite, which still passes.
[ Risks ]
The patch is already part of indent 2.2.13 and it's taken directly
from the git repository, and it fixes the memory handling problem
and nothing else.
[ Checklist ]
[X] *all* changes are documented in the d/changelog
[X] I reviewed all changes and I approve them
[X] attach debdiff against the package in (old)stable
[X] the issue is verified as fixed in unstable
[ Changes ]
Add 02-restore-round-up-macro-and-adjust-initial-buffer-size.patch.
No other changes.
[ Other info ]
The package is already uploaded.

+From: Andrej Shadura <and...@shadura.me>
+Subject: Restore the ROUND_UP macro and adjust the initial buffer size.
+Bug-Debian: https://bugs.debian.org/1036851
+
+When need_chars was moved from "handletoken.h" to "handletoken.c",
+the ROUND_UP macro was removed, but the replacement was incorrect.
+
+This caused the program to exit with a "Virtual memory exhausted"
+error when it tried to reallocate 0 bytes (thus freeing the memory).
+It reallocated to 0 bytes because the initial buffer size was less
+than 1024, and the size calculation rounds down instead of up.
+
+Bug: #56644
