<pre>
    Between LLVM 20.1.0 rc2 and rc3, a regression occured on all targets I tested (Solaris/sparcv9, Solaris/amd64, Linux/x86_64):
```
+  Flang :: Lower/namelist.f90
```
The log shows
```
/var/llvm/reltest/llvm-20.1.0/rc3/llvm-project/flang/test/Lower/namelist.f90:143:14: error: CHECK-NOT: excluded string found in input
! CHECK-NOT: bbb
 ^
<stdin>:188:41: note: found here
 fir.global linkonce @_QQclX20c1e7bd8d11bbb326c25aa979b5cad7 constant : !fir.char<1,77> {
 ^~~
```
Apparently the `CHECK-NOT` needs to be tightened not to match `bbb` inside arbitrary strings.

I tried to test `main`, too, but the build currently fails for me with an assertion failure.
