Winsock2 calls with #include causes program to crash

[Sriram Mokkapati]

Hi all please give me a solution for this

Help please.

Below is a small simple C program created with MS Visual C++ v6sp5.

When the EXE (saserver.exe) is run on 2 different MS Windows XPsp1 machines,
the program crashes - see the attached "PerlAndWinsockBomb.jpg" image.

If I take out the "#include <perl.h>" line OR if I take out the the
"listenSocket = socket(AF_INET, SOCK_STREAM,IPPROTO_TCP);" line
and recompile/link, then the program does not crash - it finishes without a
problem.

The embedded Perl code (not included) that I *must have* the "#include
<EXTERN.h>" and "#include <perl.h>" lines for works fine in any C code I
build that does not have any C Winsock socket calls in them. However, the
embedded Perl code seems irrelevant to this particular email message since I
can't even include (#include <perl.h> it's prerequisites without the
program crashing.

Please help. Any ideas or thoughts or intuitions will be appreciated.
