Compile a file consecutive several times makes TOLBase to crash

[César Pérez Álvarez]

If we compile this file several consecutive times TOLBase will crash. The number of times that we have to compile is not always the same.

FILE : error.tol
PURPOSE:

Date Ini = y2006m05d01;
Date End = y2006m07d24;
Serie stepIn = SubSer(CalInd(C, Semanal), Ini, End);

Serie forma1 = DifEq(1/(1-0.4*B), stepIn);

Only a comment. This nehaviour does not happend in version 115.

verified also on Linux/TOL-1.1.7

I've reproduce this error in a simple way with a TOL "For" cycle

Set aux = For(1,5, Real(Real k)
{

WriteLn("Evaluation "+IntText(k));
Date Ini = y2006m05d01;
Date End = y2006m07d24;
Serie stepIn = SubSer(CalInd(C, Semanal), Ini, End);
Serie forma1 = DifEq(1/(1-0.4*B), stepIn);
k

});

First 3 iterations seems to work fine but TimeSet Semanal is lost after fourth one:

Problem has been fixed in CVS

NameBlock members must be treated as global or system variables when are used as the dating of a time serie. Now, Semanal is a member of StdLib instead a global variable and it was be taked as a local one by local variables Serie stepIn and Serie forma1 that must ensure to destroy its own dating, believing that it was also local.

Thanks to report it
