hi all
i am studing the openssl api. i down the source code from ibm.
url http://www-128.ibm.com/developerwork...l-openssl.html

when i use MSVC 7.1 +boundchecker. the compiler told me memory leak

LIBEAY32.dll 0x 000001fc5

from C:\Program Files\Microsoft Visual Studio .NET
2003\Vc7\crt\src\crt0.c

#else /* WPRFLAG */
__initenv = _environ;
mainret = main(__argc, __argv, _environ); <== this
line
#endif /* WPRFLAG */

LIBEAY32.dll 0x 000001fDA

memory leak 4k

can you tell me it is bug of code ? or openssl ? maybe windows?

thanks
