Bug ID: 112491
Summary: std::deque<T,Allocator>::size xmethod output is wrong
Product: gcc
Version: 13.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: ks1322 at gmail dot com
Target Milestone: ---
For this code:
```
#include <deque>
int main()
{
std::deque<int> d;
d.push_front(0);
return 0;
}
```
deque size xmethod produces wrong result
```
$ gdb -batch -ex "b 8" -ex r -ex "p d.size()" a.out
Breakpoint 1 at 0x4011f5: file /tmp/t.cpp, line 8.
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".
Breakpoint 1, main () at /tmp/t.cpp:8
8 return 0;
$1 = 128
```
Expected result is 1 while actual result is 128.
As a workaround xmethods can be disabled with `disable xmethod`
```
$ gdb -batch -ex "b 8" -ex r -ex "disable xmethod" -ex "p d.size()" a.out
Breakpoint 1 at 0x4011f5: file /tmp/t.cpp, line 8.

$1 = 1
```
