This workarounds: http://ix.io/1xOT which worked perfectly fine in older libfmt versions

@DanielaE could you take a look?

Hallo Peter!

With commit e015792, {fmt} tightened the parsing of literal integral fields in the formatting specification such that they no longer are allowed to start with zeros. This aligns the parsing within the formatting specification string to the same parsing rules of decimal integer literals outside of strings as defined in C or C++. In fact, after some roaming the internet for printf formatting specifications I've never encountered any example which would show an integer literal with leading zeros. Seemingly leading zeros are not part of integral literals but a formatting specifier on their own which cannot happen in the precision field.

The crash that you are experiencing is probably due to the exception thrown in the parser of the printf-type syntax.
