This is to fix #3778. When loading booster from a model file produced by old version of LightGBM without linear tree option, we should set is_linear_ of a tree to false, to avoid uninitialized is_linear_ value, which can cause undefined behavior.

@shiyu1994 we are still battling some instability in continuous integration haha

Once #4054 and #4053 are merged, the build failures you're seeing here should be fixed.They are both approved, just waiting for builds to finish. Should be done in the next 1-2 hours.

Sorry for the inconvenience.

I've been biten by this bug and just figured out the problem.

Loading a model generated by previous version of LightGBM which does not have is_linear=0. This leads to uninitialized is_linear_ instance variable and leads to wrong predict values.

* remove duplicate functions from merge

* Fix parsing of non-finite values.  Current implementation silently returns zero when input string is "inf", "-inf", or "nan" when compiled with VS2017, so instead just explicitly check for these values and fail if there is no match.  No attempt to optimise string allocations in this implementation since it is usually rarely invoked.

* Dummy commit to trigger CI

* Also handle -nan in double parsing method

* Update include/LightGBM/utils/common.h

Remove trailing whitespace to pass linting tests
