Hello all!

Writing an application under WARP (using SpeedPascal/2), I decided to
incorporate a secondary thread for some lengthy generation-operations that
were only in very rare cases _not_ to violate the 1/10th rule.

I did not incorporate this at first, since I had trouble enough writing for
PM as it is.

My problem is this: I start the thread with a stack of some size (tried
different sizes). 
Then the thread-function calls some routines local to the application.
Nothing wrong yet, but as soon as I want to initialise the thread to open
an Object window, using WinInitialize, I get a Guardpage exception. (I
tried sizes: $4000,32768,81*1024*1024)

I did not install an exception handler for this secondary thread, but the
compiler's runtime-library does not seem to install one for the main thread
and does not seem to have any problems in stack-expansion.... 

Who can help me solve this problem? (or has had any problem like it?)

I could write an exception-handler that uses the guardpage-system to expand
the stack, but the operating system is supposed to be able to do that
itself...

Bye, Erik!

PS: I did try to run the thread using the Commit-stack option. This does
the trick, but I don't want to be placed back into the 16-bit age where I
need to try to determine the max. size my stack will grow to.
