[Mingw-users] Crash in SSL_library_init: possible linking issue

[Jonathan P. <jp...@to...>]

Hi all,

I'm trying to use OpenSSL under an MinGW environment under Windows 7 
64-bit. I was able to build and use glib based applications without 
problems using packages provided at:

http://www.gtk.org/download/win32.php

When I try to use OpenSSL, it always crash (Segmentation fault) in 
SSL_library_init. I'm using the "msys-openssl" packages installed using 
mingw-get.exe. Here is a simple example to illustrate the problem. If I 
compile this:

---
#include <openssl/ssl.h>

int
main(int argc, char **argv)
{
     SSL_library_init();

     return 0;
}
---

by using this command:

---
gcc -IC:/MinGW/msys/1.0/include   -g -Wall ssl_demo.c -o ssl_demo.exe 
-Wl,--enable-auto-import -LC:/MinGW/msys/1.0/lib -lssl -lcrypto
---

The resulting binary will crash deep within SSL_library_init. The flags 
and library linking used above were determined using:

---
PKG_CONFIG_PATH="/lib/pkgconfig" pkg-config --cflags --libs openssl
---

My OpenSSL installation appears to be running correctly if I use the 
command line driven "openssl.exe". I suspect a linking issue given this 
output:

---
$ ldd-light /bin/openssl.exe
/bin/openssl.exe:
         DLL Name: msys-crypto-1.0.0.dll
         DLL Name: msys-ssl-1.0.0.dll
         DLL Name: msys-1.0.dll
         DLL Name: KERNEL32.dll
         DLL Name: msys-crypto-1.0.0.dll
         DLL Name: msys-crypto-1.0.0.dll

$ ldd-light ssl_demo.exe
ssl_demo.exe:
         DLL Name: KERNEL32.dll
         DLL Name: msvcrt.dll
         DLL Name: msys-ssl-1.0.0.dll
---

I tried countless linking variations and the problem still remain. I 
managed to remove the dependency on "msvcrt.dll", which I believe to be 
the source of the problem using "-nostdlib" but it was simply crashing 
elsewhere in "__main".

Anybody knows how to properly link OpenSSL application in MinGW or I've 
hit a real problem?

Thanks,
