Describe the bug

Here's a failed compilation with BPF-clang: https://godbolt.org/z/9er5dzxTj
The error message is -

<source>:3:12: error: unsupported dynamic stack allocation
3 |     return alloca(num);
  |            ^
1 error generated.
Compiler returned: 1

As it should be. If, however, you open opt-remarks or stack-usage - the error message reduces to just "Compiler returned: -1" and the asm output begins with:

<Compilation failed: Cannot read properties of undefined (reading 'filter')>

or

<Compilation failed: Unwrap failed, at https://static.ce-cdn.net/main.v47.08ed3e3bbe1ba59de1d1.js:1>

for opt-remarks / stack-usage accordingly.
