--- Comment #19 from Icenowy Zheng <uwu at icenowy dot me> ---
Well I am not sure whether this is a libstdc++-specific problem:
```
(ssh)root@musebook [ ~ ] # gcc test.c -Wl,-Bstatic -lz -Wl,-Bdynamic
(ssh)root@musebook [ ~ ] # nm -D a.out
U aligned_alloc@GLIBC_2.27
w __cxa_finalize@GLIBC_2.27
U free@GLIBC_2.27
w _ITM_deregisterTMCloneTable
w _ITM_registerTMCloneTable
U __libc_start_main@GLIBC_2.34
0000000000000842 T main
U puts@GLIBC_2.27
(ssh)root@musebook [ ~ ] # ldd a.out
linux-vdso.so.1 (0x0000003f9854a000)
libc.so.6 => /usr/lib/libc.so.6 (0x0000003f9838a000)
/lib/ld-linux-riscv64-lp64d.so.1 =>
/usr/lib/ld-linux-riscv64-lp64d.so.1 (0x0000003f9854c000)
(ssh)root@musebook [ ~ ] # ./a.out
1.3.1.zlib-ng
(ssh)root@musebook [ ~ ] # nm -D /usr/bin/gcc | grep cxx | wc -l
226
(ssh)root@musebook [ ~ ] # cat test.c
#include <zlib.h>
#include <stdio.h>
int main()
{
printf("%s\n", zlibVersion());
}
```
Statically linking a zlib-ng here does not pollute the dynamic symbol list of
my executable.
