My version: 8dfdcc7b7 (grafted, tag: llvmorg-15.0.7, origin/release/15.x, release/15.x)
# Description:
I build a debug version to debug and learn MLIR
When I debug `toyc-ch7` by GDB, I found it will take too much time to show stack information using gdb command `breakpoint`
# Steps to reproduce
## 1. build debug version mlir
## 2. add `source /your path/utils/gdb-scripts/prettyprinters.py` to ~/.gdbinit
## 3. reproduce command
- gdb binary
```bash
gdb /you path/bin/toyc-ch7
```
- in gdb environment
```bash
set args /your path/llvm-project/mlir/test/Examples/Toy/Ch7/struct-ast.toy -emit=mlir --mlir-disable-threading
b StructTypeStorage::StructTypeStorage
r
bt
```
- When I run bt command two times, it will take much time to show stack information
