One is the general problem of how one would build Perl with 'NO_PERL_PRESERVE_IVUV' and the circumstances where one would want to do that. The other is any Win32-specific problem, such as getting tests to pass once we have figured out how to build with this option. For the reference of anyone who can address this ticket, here's some relevant source code: from perl.h: ### #ifndef NO_PERL_PRESERVE_IVUV #define PERL_PRESERVE_IVUV /* We like our integers to stay integers. */ #endif ### ... and this comments precedes several tests in ext/Devel-Peek/t/Peek.t ### # If perl is built with PERL_PRESERVE_IVUV then maths is done as integers # where possible and this scalar will be an IV. If NO_PERL_PRESERVE_IVUV then # maths is done in floating point always, and this scalar will be an NV. # ([NI]) captures the type, referred to by \1 in this regexp and $type for # building subsequent regexps. ### Rob, have you had any further experience with this bug since originally filing the ticket? Thank you very much. Jim KeenanThread Next
