Here's the reproducer for the OOM issue: [repro.cc](https://github.com/user-attachments/files/19391674/repro.txt)

With `clang` before this PR run this to show the compilation does not need more than 150MB memory:

```
# $(ulimit -Sd 150000;  \
   clang.before -cc1 -triple x86_64-generic-linux-gnu -emit-obj -target-cpu x86-64 \
     -O1 -std=gnu++20 \
     -o /tmp/repro.o  \
     /tmp/repro.cc) 
```
 
With `clang` at this PR run this to show the compilation exceeds 600MB memory use:
```
#  $(ulimit -Sd 650000;  \
      clang -cc1 -triple x86_64-generic-linux-gnu -emit-obj -target-cpu x86-64 \
         -O1 -std=gnu++20 \
         -o /tmp/repro.o \
         /tmp/repro.cc)
```
