Summary: -m32 forbids empty scalar initializer
Product: gcc

test case
$ gunzip a.c.gz
$ gcc -c a.c
[ no output ]
$ gcc -m32 -c a.c
doprnt.c: In function ‘_doprnt’:
doprnt.c:144:27: error: empty scalar initializer
144 | va_list to_be_printed = {}; /* argument to be printed if
numeric specifier are used */
| ^
doprnt.c:144:27: note: (near initialization for ‘to_be_printed’)
I tried the trivial test-cases, but they pass.
But in this particular file any empty scalar initializers
are forbidden with -m32.
