#GP4 tester error

[amarjen]

Hello,

I’m having issue passing #GP4 but not sure why.

If I do codecrafter test , it goes well with this output:

[tester::#GP4] Running tests for Stage #GP4 (Navigation - The cd builtin: Home directory)
[tester::#GP4] Running ./your_program.sh
[your-program] $ cd /tmp/grape/strawberry/strawberry
[your-program] $ pwd
[your-program] /tmp/grape/strawberry/strawberry
[tester::#GP4] Received current working directory response
[your-program] $ cd ~
[your-program] $ pwd
[your-program] /tmp/apple/pear/apple
[tester::#GP4] Received current working directory response
[your-program] $
[tester::#GP4] Test passed.

Then, I do codecrafter submit, and it throws a weird result:

[tester::#GP4] Running tests for Stage #GP4 (Navigation - The cd builtin: Home directory)
[tester::#GP4] Running ./your_program.sh
[your-program] $ cd /tmp/mango/grape/grape
[your-program] $ pwd
[your-program] /tmp/mango/grape/grape
[tester::#GP4] Received current working directory response
[your-program] $ cd ~
[your-program] $ pwd
[your-program] malloc(): invalid size (unsorted)
[tester::#GP4] Output does not match expected value.
[tester::#GP4] Expected: "/tmp/raspberry/pear/pineapple"
[tester::#GP4] Received: "malloc(): invalid size (unsorted)"
[tester::#GP4] Assertion failed.
[tester::#GP4] Test failed

I’m doing something wrong, or the tester has a bug?

Thanks,

Hey @amarjen, it was likely a tester bug that allowed the code to pass the first time.

Passing ~ directly into chdir will not work as expected:

You’ll need to expand ~ to the full path for chdir to work properly.

Let me know if you’d like further clarification!
