Hi Folks!

I recently had some problems with “stack overflow” in my programs so I decide to enlarge /STACK in linker to 10MB ( /STACK: 10485760, 10485)… Now I’m experiencing new problems that my app runs out of memory so new problem for me. Does anyone use this STACK feature in linker and how to measure what’s the right size of stack. And if anyone use this please write me how much of stack did you put because in Alaska help there is no detailed explanation.


Thanks, Goran

Hi, Goran.

"Stack overflow" comes in the context of a not-ending recursion. Check the XppFatal.log for the cause.

Anyway, this is what I use:

/STACK:5000000,10000

I have never had a stack overflow unless it was caused by an error in recursion.
I believe that the stack defaults to 1000. It is nearly impossible to write code that would blow that stack.

Hi Roger,

Till now there was no problem with alaska 1.9, but after we change to 2.0 we expereiencing big, big problems with stack overflow and shutting down program WITHOUT ANY ERROR !!!

for example, DC print;
------------------------------------------------
Export_File='C:\TEMP\Prijemni list-kalkulacija '+Slozi_Broj(AllTrim(UT->Sifra),ID,DATUM)+".PDF"
FErase(Izlazna_Datoteka)
IF cOption = "PREVIEW"
DCPRINT ON SIZE 60, 155 TO oGrcPrinter FONT '9.Arial CE' NOSTOP ORIENTATION 2 TITLE 'Prijemni list-kalkulacija '+Slozi_Broj(AllTrim(UT->Sifra),ID,DATUM) CANCELENABLE BUSYMESSAGE 'Pripremam dokument' NAME "Bullzip PDF Printer" OUTFILE (Izlazna_Datoteka) ACROBAT NOSPAWN
ELSE
DCPRINT ON SIZE 60, 155 TO oGrcPrinter FONT '9.Arial CE' NOSTOP ORIENTATION 2 TITLE 'Prijemni list-kalkulacija '+Slozi_Broj(AllTrim(UT->Sifra),ID,DATUM) CANCELENABLE BUSYMESSAGE 'Pripremam dokument'
ENDIF

if I print to printer (not preview) everything is OK, but if cOption is Preview i receive this error:

Take out the CANCELENABLE and BUSYMESSAGE and see if you still get the error.
