Fixes 2 Bugs and 13 Compiler Warnings (#10670)

* fixes: %g directive writing between 1 and 13 bytes into a region of size between 6 and 18 [-Wformat-overflow=]

* fixes: %5s directive writing between 5 and 63 bytes into a region of size 58 [-Wformat-overflow=]

* fixes: catching polymorphic type by value [-Wcatch-value=]

* fixes: [-Wcomment]; removes whitespaces

* increases buffer size from 71B to 90B to avoid potential ovfl.
