Linux cruncher 2.6.9-gentoo-r14 #6 Tue Mar 1 21:09:07 CET 2005 x86_64 AMD Athlon(tm) 64 Processor 3200+ AuthenticAMD GNU/Linux
gcc version 3.4.3 20050110 (Gentoo Linux 3.4.3.20050110, ssp-3.4.3.20050110-0, pie-8.7.7)
This GDB was configured as "x86_64-pc-linux-gnu".
>Description:
It is not possible to print out the value of members of unnamed structs (possibly unions too).
Bug existed at least in 6.0.
>How-To-Repeat:
gpiez@cruncher ~ $ cat test.c
union {
int all;
struct {
char part1;
char part2;
};
} foobar = { .all = 257 };
main() {
printf("%d\n", foobar.all);
printf("%d\n", foobar.part1);
}
gpiez@cruncher ~ $ gcc -g -o test test.c
gpiez@cruncher ~ $ ./test
257

gpiez@cruncher ~ $ gdb test

(gdb) print foobar.all
$1 = 257
(gdb) print foobar.part1
There is no member named part1.
