Source: mdbtools
Version: 1.0.0+dfsg-1.3
Severity: serious
Tags: ftbfs patch upstream

Dear maintainer,
Starting with GCC 14, mdbtools fails to build on a few architectures,
mips64el, ppc64el, riscv64 and s390x for official architectures and
loong64, powerpc, ppc64 for ports architectures:
| odbc.c: In function '_odbc_fix_literals.isra':
| odbc.c:1998:35: error: 'quote_char' may be used uninitialized [-Werror=maybe-uninitialized]
| 1998 | } else if (quoted && *s==quote_char) {
| | ~~~~~~~^~~~~~~~~~~~~~~~~
| odbc.c:1990:14: note: 'quote_char' was declared here
| 1990 | char quote_char;
| | ^~~~~~~~~~

A full build log is available there:
https://buildd.debian.org/status/fetch.php?pkg=mdbtools&arch=riscv64&ver=1.0.0%2Bdfsg-1.3%2Bb1&stamp=1730341733&raw=0
It appears that on those architectures, GCC 14 is unable to make the
link between the quoted and quote_char variables. A fix has already been
sent as a PR upstream:
