           Summary: FormatCurrency(9) returns .9.00 (period in front)
           Product: Wine
           Version: 4.0-rc5
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal

Created attachment 63224
  --> https://bugs.winehq.org/attachment.cgi?id=63224
compiled executable

Reproduced in wine-3.0.4 in Linux Mint, wine-3.18-staging in Sabayon (from its
package manager) as well as self-compiled (vanilla) wine-3.21-298-ge9231beb86
and wine-4.0-rc5-14-g0ff7fd1259

FormatCurrency(9) returns ".9.00", notice the period in the front.
Therefore, FormatCurrency(FormatCurrency(9)) will segfault.
Why does it add the period there?
