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. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
