Subject: libphonenumber FTBFS with gcc-15 and -Wbidi-char
Package: libphonenumber8
Source: libphonenumber
X-Debbugs-Cc: [email protected]
Version: 8.13.51+ds-4.2
Severity: normal
attempting to compile libphonenumber with Ubuntu defaults with gcc-15
results in a FTBFS. This is due to -Werror=bidi-char being set by default.
-Wbidi-char raises

cc1plus: all warnings being treated as errors
Where <U+200F> in the code is the properly formatted Unicode character.
The test correctly encodes it, and only the comment contains the unicode
literal. However, -Wbidi-char checks comments as well, as that is a source
for a Trojan Source attack. pragma comments also cannot disable bidi-char
when set via cli or envvar.
Attached is the proposed patch going into Ubuntu, which escapes the
comment. This is also reported upstream with Google, where I suggest
escaping as well.

Description: Escape unicode bidi-char in comment
gcc-15 default in Ubuntu runs with -Werror=bidi-char=.
Bidi-char warnings are not supressable with pragma.
Instead, escape the comment into <> instead of [] so it
is not interpreted as unicode.
