| ## For regular sections, it is common to specify `Size` and/or `Content` fields in YAML. |
| ## Here we test the behavior in different cases. |
| |
| ## In this case, we have both `Content` and `Size` fields specified and `Size` |
| ## is less than content size. Check we report an error. |
| |
| # RUN: not yaml2obj --docnum=1 %s -o %t1 2>&1 | FileCheck %s --check-prefix=ERR |
| # ERR: error: Section size must be greater than or equal to the content size |
