A minimal cpp file to reproduce the issue is
```cpp
// example.cpp
int main()
{
try
{
return 0;
}
catch (...)
{
return 1;
}
}
```
Then passing clang-query the commands
```
# cmd.txt
set output dump
set traversal IgnoreUnlessSpelledInSource
match stmt()
```
Invoking `clang-query example.cpp -p <build_dir> -f cmd.txt` will seg fault with stack trace
```

Notably using AsIs traversal is not affected by this issue
```
# cmd_as_is.txt
set output dump
set traversal AsIs
match stmt()
```
``clang-query example.cpp -p <build_dir> -f cmd_as_is.txt`` does not not seg fault
