Wrong return value

Subject: https://github.com/rfalke/decompiler-subjects/tree/master/from_holdec/dmi/cfg/ia32_elf/subject.exe

Output
```
int32_t advanced_20_jump_table_on_stack(uint32_t result) {
if (result < 6) {
// 0x8048f6c
return result;
}
// 0x8048f70
puts("is something else");
return 0;
}
```

The first return should also have a value.

Reproduce the output from the linked subject.exe, focusing on advanced_20_jump_table_on_stack and its jump-table-on-stack handling; no repository file or test is named in the report. Determine the expected value for the first branch and confirm that the generated decompilation returns that value.
