The more I look at this the more I think it is potentially a bug with gcc.
For example, if I produce an MRE like:
```cpp
#include "absl/synchronization/mutex.h"
void foo() {
auto var = absl::Mutex{};
var.Lock();
}
```
and compile that with g++-14:
```shell
$ g++-14 -Iliblib.so.p -I. -I.. -fdiagnostics-color=always
-D_GLIBCXX_ASSERTIONS=1 -D_FILE_OFFSET_BITS=64 -Wall -Winvalid-pch -O0 -g -O0
-fPIC -DNOMINMAX -MD -MQ liblib.so.p/src.cc.o -MF liblib.so.p/src.cc.o.d -o
liblib.so.p/src.cc.o -c ../src.cc
```
then no errant symbol appears:
```shell
$ objdump --syms liblib.so.p/src.cc.o | grep Dtor
```
If I run the same command but symbol reference a compiler installed by the
conda compilers package:
```shell
$ $ g++-14 -Iliblib.so.p -I. -I.. -fdiagnostics-color=always
-D_GLIBCXX_ASSERTIONS=1 -D_FILE_OFFSET_BITS=64 -Wall -Winvalid-pch -O0 -g -O0
-fPIC -DNOMINMAX -MD -MQ liblib.so.p/src.cc.o -MF liblib.so.p/src.cc.o.d -o
liblib.so.p/src.cc.o -c ../src.cc
```
then the errant reference appears:
```
$ objdump --syms liblib.so.p/src.cc.o | grep Dtor
0000000000000000 *UND* 0000000000000000

```
On ubuntu 24.04 it looks like g++-14 provides version 14.2, whereas conda
provides 14.3. So perhaps there is a regression between the minor versions
