Modeling algorithms - the length of result shape differs from reference value

On compiler MinGw 12.1.0
test
hlr poly_hlr bug25813_3
fails with error:

The length of result shape is 302.443, expected 301.999.

P.S.
This test marked BAD for Linux. So, if we use gcc on Windows, it is waitable, that length of shape is aligned with shape length on Linux:
puts "TODO OCC30286 Linux: Error : The length of result shape is 302.443, expected 301.999"

To solve the problem we should add something like that:
puts "TODO OCC30286 Linux: Error : The length of result shape is 302.443, expected 301.999"
at the begin of test scenario, but only for MinGw compiler, not MSVC. The way of defining compiler name for tcl should be developed.
In other case, the test would be BAD not only for Linux, but for Windows too, independently from compiler.
