Maybe you remember me, I am the man that refreshed stunnel for winCE up
to 4.27 version.
Thank you for having included my code to your mainstream at that time.
As a win32 regular programmer I always check that my code is as close as
possible as that of the main win32 stream for PC.
I am writing you today to point out a critical bug that prevent stunnel
4.34 from servicing any service at all .
I have fixed that bug and will send you a refresh of all the sources
(that needed some after some win32 PC version updates) soon.
SO DO NOT DO ANYTHING.
the bug is in sthread.c:
the wince _beginthread port has been modified (by someone else but me)
as this :
the "STACK_SIZE_PARAM_IS_A_RESERVATION" flag is the novelty from 4.27.
The problem is that beginthread is being called from gui.c with stacksize=0
SO THAT a stack of 0 size "TRIES to be RESERVED" and then CreateThread
FAILS to return a valid handle.
That is to say that no thread is created, and thus NO TUNNELING SERVICE
at all can be delivered.
So stunnel cannot work at all.
Solution : the proper call is :
(stack_size > 0) ? STACK_SIZE_PARAM_IS_A_RESERVATION:0,
I repeat and insist : please DO NOT DO anything to the code, as I will
send soon a refresh with various other updates (because apart from that
the code needs other refresh to compile properly),
and as I am also working on a refresh of openssl up to 1.0.0a (those
gentlemen at openssl never included any wce patch to their mainstream,
which is really a pity, but another story).
See you soon,
Thank you again for all the work you do for the community of people,
