Yes. Unfortunately that old database is gone for good.
Do someone know how has it been resolved?
It has been resolved using the rtl::math::isFinite() check which in turn
uses the SAL_MATH_FINITE macro which is interestingly defined in a
platform-dependent way in main/sal/inc/sal/mathconf.h
What may be a problem is that the way the macro is defined for OS/2 it
does not reliably work if it is called via the rtl::math::isFinite()
function, because then the sizeof(type) magic fails.
Does it help if you replace the call to that inline method isFinite() to
the macro SAL_MATH_FINITE()?
This bug is present when users show the page settings dialog to select
margins and page size. Since it happens when very big numbers are used
forI found a workaround using
mnMax = 0x00000000FFFFFFFFLL;
as initializer in void NumericFormatter::ImplInit()
This sounds like a reasonable plan-B though I'm a bit worried to limit
the value to 32bit because it was defined as 64bit for a reason.
