Unfortunately, its been several weeks since the last time IVF 9.1
found a uninitialized variable at runtime that Lahey 7.1 did not. All
I remember is that it was in a module procedure.
For years, I have depended on Lahey's runtime checking although I was
aware of some of its quirks. For example, they "set" uninitialized
data to a specific bit pattern (a different one for each data type)
and then check for that pattern at runtime. The problem I ran into is
that their integer(1) pattern was valid data for me!
I have been using Lahey compilers since f77l (only a ~100kB
executable!) in the 1980's. I will miss having an up-to-date version
of one of their Windows compilers. The aforementioned contact with
one of their representatives was for a bug that was known but will
sadly never get fixed.
