Hello:
I compiled openssl-0.9.5 for Visual C++,following the
instructions of Andrew Gray, and everything looks work
fine; but I encounter a problem with the BIO functions
that I can resolve. Here is the code:
#include <stdio.h>
#include <openssl/ssl.h>
int main() {
pBioErr= BIO_new_fp(stderr,BIO_NOCLOSE);
fwrite("Hello world\n", 11, 1, pBioErr->ptr);
BIO_printf(pBioErr, "Hello, world\n");
return(1);
};
The program crash in BIO_printf(...), with the next
call stack:
NTDLL! 77f7ce4c()
NTDLL! 77f77586()
fwrite(const void * 0x0012f70c, unsigned int 6,
unsigned int 1, _iobuf * 0x00422a98) line 72 + 9 bytes
file_write(bio_st * 0x009c1fb0, char * 0x0012f70c, int
6) line 172 + 23 bytes
BIO_write(bio_st * 0x009c1fb0, const char *
0x0012f70c, int 6) line 197 + 20 bytes
BIO_printf(bio_st * 0x009c1fb0) line 95 + 20 bytes
main(int 1, char * * 0x00ad0e90) line 25 + 14 bytes
mainCRTStartup() line 206 + 25 bytes
KERNEL32! 77f1b9ea()
And the debug window display this:
Loaded 'D:\WINNT\System32\ntdll.dll', no matching
symbolic information found.

First-chance exception in leaks.exe (NTDLL.DLL):
0xC0000005: Access Violation.
I think its very strange that the same function call
(fwrite) with the same parameters that works in
main(), fails in file_write(). Maybe is a problem with
the settings of the compilation, because the utility
applications (openssl, etc) works ok.
Anyone could help me?
Thanks in advance.
