--- Comment #2 from Felix Hädicke  ---
Analyzed the problem further. Compiled msvcr90 with and without Ryzen
optimisations. Then changed the optimisation settings for specific files.

Found out that it is enough to disable -march=znver2 for wcs.c to make it work.
Then I found out that it is enough to disable optimisations for the function
puts_clbk_str() in printf.h. Used __attribute__((optimize("O0"))) for this
function.
