Revision 86057528ebd297aa57c857bf4a03f691f0eb9425 authored by Étienne Mollier on 16 June 2021, 18:19:11 UTC, committed by Étienne Mollier on 16 June 2021, 18:19:11 UTC 
fix test suite discrepancies on 32 bit
 
Some differencies showed up in some of the tests.  It turned out that some
more overflows are occurring, but were not caught at build time.
These adjustments allow the test suite to pass again.  There are no
changes of behavior on 64 bit platforms.
