Not a bug, but by design - the behavior of strtod() is locale-dependent.
In locales where ',' is treated as a decimal point (such as
pl_PL.UTF-8), strtod("0,1") returns 0.1 (the value 1/10); in locales
where '.' is decimal point (such as en_US.UTF-8), it returns 0 with ",1"
as trailing garbage.

strtod() always parses "." as a decimal separator regardless of what
other characters it might ALSO parse depending on locale.  Beyond that,
it is your responsibility to be aware of what locale your script is using.
