## Check how yaml2obj produces .stack_sizes sections.
## Test the following cases when the .stack_sizes Content field is specified:
## 1) We can produce a .stack_sizes section from a description with
## a valid section content.
## 2) We can produce an incorrect .stack_sizes section from a description with
## a broken (truncated) section content.
## 3) We can produce an empty .stack_sizes section from a description with
## empty section content.
