    Hi! I cannot figure out a reason of not working of 'step-avoid-regexp' for my executable, so created this issue.

Preconditions:
```bash
lldb version 16.0.6
python 3.10 x64
LLDB_USE_NATIVE_PDB_READER=1
```

If `LLDB_USE_NATIVE_PDB_READER=1` is not set lldb crashes on, for example, "fr v". 
> I unsuccessfully tried to find out why `msdia140.dll` fails by procmon. So decided to switch to native pdb reader.

I compile with `msvc` and use `/Ob1` to avoid inlining, and doublechecked source files are correctly opened when reached a breakpoint.

Typical compilation command (extra options removed)
`
cl.exe /MDd /external:W0 /external:templates- /DUNICODE /D_UNICODE /Od /c path/to/source/file.cpp /nologo /Z7 /bigobj /Zc:forScope /Zc:inline /Zc:wchar_t /fp:precise /D_CRT_NONSTDC_NO_WARNINGS /D_CRT_SECURE_NO_DEPRECATE /D_CRT_SECURE_NO_WARNINGS /D_SCL_SECURE_NO_WARNINGS /DWIN32 /D_WINDOWS /D_WINSOCK_DEPRECATED_NO_WARNINGS /DWINVER=0x0600 /D_WIN32_WINNT=0x0600 /DNTDDI_VERSION=0x06000000 /W3 /guard:cf /GR- /EHsc /guard:ehcont /source-charset:windows-1251 /execution-charset:windows-1251 /Oy- **/Ob1** /WX /wd4996  /wd4117 -D__DATE__="redacted" /RTC1
`

Launching and configuration:
```bash
lldb.exe proc.exe
> settings set target.source-map . F:/prj/mono/src
> settings set target.process.thread.step-avoid-regexp ^.*(std::|boost::).*$
> b main
> r
> si
```

But anyway step-into falls to `std::` and `boost::` functions which I expect should not happen.

Even more: if I set regexp=.* nothing changed.

- Is this behaviour expected?
- May this happen because of preconditions (especially `LLDB_USE_NATIVE_PDB_READER=1`)? 
- Any recommendation or workarounds?

TY
