memory allocation error after raised Exception and catched in 2.0.2?

[itsumura-h]

Description

I'm creating relatively large web application in Nim. I found a SIGSEGV: Illegal storage access. error happen after only raised Exception and catched safety. I tried to create simple example but it seems only for relatively large program. And it not happen when using Nim v2.0.0. Only in 2.0.2.

reproduction scenario

1. Clone application from github

   git clone https://github.com/itsumura-h/realworld-basolato-htmx

2. Run docker container. 8000 port on host need to be free.

   cd realworld-basolato-htmx
   git switch alloc-error
   docker compose build
   docker compose up -d
   docker compose exec app bash
   cd /root/project/src
   choosenim 2.0.2

3. install dependency packages

   nimble install -y -d

4. create .env file copy .env.eample to .env DB Connection section should be as bellow

DB_DATABASE="database" # sqlite file path or database name
DB_USER="user"
DB_PASSWORD="pass"
DB_HOST="postgres"  # host ip address
DB_PORT=5432 # postgres default...5432, mysql default...3306
DB_MAX_CONNECTION=10 # should be smaller than (DB max connection / running num processes)
DB_TIMEOUT=30 # secounds

5. run migration and seed for database

   ./resetDb.sh

6. run application

   ducere serve

7. access browser http://localhost:8000/

8. sign in http://localhost:8000/sign-in

   email: test@example.com
   password: password

9. access setting page http://localhost:8000/settings click Update Settings button without filing password

10. In the top of the screen, you can see error messages as expect

11. Click the left top icon to go top page, but it not moved. If you check the terminal, you can see the error message like this

My speculation

In the No.10, this error is raised src/app/models/aggregates/user/vo/password.nim as DomainError and catched in update proc insrc/app/http/controllers/htmx_setting_controller.nim

However, after catched error and responde safety, something memory management seems to be broken and Illegal storage access error happen in the next time access.
