February 2006 and the file is called "Win32OpenSSL-v0.9.8a.exe". I didn't have any OpenSSL stuff on my computer before, so even no "old things" lieing around on the harddisc. If I run the program in VS .net 2003 v7.1.3088 with "Start F5" the program seems to "freeze" at PEM_read_RSAPrivateKey, consumes 100% usage of one CPU (I have a Hyperthreading so I see 50% CPU usage in task manager) and when I press "Break All" in the Debugger I get the following call stack: ---------- snip ---------- msvcrt.dll!77c12b9f() ntdll.dll!7c9206eb() ntdll.dll!7c97d886() ntdll.dll!7c959d18() ntdll.dll!7c92b686() ntdll.dll!7c936a44() ntdll.dll!7c936abe() ntdll.dll!7c936abe() ntdll.dll!7c97cde9() ntdll.dll!7c97e0f0() ntdll.dll!7c97e0d4() ntdll.dll!7c92b5f4() ntdll.dll!7c92b686() ntdll.dll!7c936abe() ntdll.dll!7c97cde9() ntdll.dll!7c97e0f0() ntdll.dll!7c95a1f5() ntdll.dll!7c92b5f4() ntdll.dll!7c92b686() kernel32.dll!7c81cb8e() kernel32.dll!7c81cbcb() ntdll.dll!7c91e3ed() ntdll.dll!7c9232f8() kernel32.dll!7c81cb8e() kernel32.dll!7c81cbcb() msvcrt.dll!77c0f962() msvcrt.dll!77bfc3ce() libeay32.dll!1000101e() libeay32.dll!1000120c() libeay32.dll!1003f487() libeay32.dll!1003d627() libeay32.dll!10068404() msvcr71d.dll!_write_lk(int fh=1, const void * buf=0x00000fa0, unsigned int cnt=270647770) Line 234 + 0x8 C msvcr71d.dll!_write(int fh=1244344, const void * buf=0x1021b45c, unsigned int cnt=1) Line 87 + 0x9 C msvcr71d.dll!_unlock_fhandle(int fh=1244344) Line 477 C 003e1fb8() msvcr71d.dll!_write(int fh=1244392, const void * buf=0x00000001, unsigned int cnt=270542996) Line 87 + 0x9 C msvcr71d.dll!_flsbuf(int ch=271042648, _iobuf * str=0x1024755c) Line 180 + 0x11 C msvcr71d.dll!fputc(int ch=10, _iobuf * str=0x1027c858) Line 56 + 0x9 C msvcr71d.dll!_tsopen_lk(int * punlock_flag=0x0000000a, int * pfh=0x1027c858, const char * path=0x0012fdb8, int oflag=273198671, int shflag=1244426, int pmode=273199175) Line 414 + 0xd C msvcp71d.dll!std::_Fputc<char>(char _Byte='<STRANGEBOXHERE>', _iobuf * _File=0x1048b047) Line 69 + 0xf C++ msvcp71d.dll!std::basic_filebuf<char,std::char_traits<char> >::overflow(int _Meta=268693911) Line 206 + 0x19 C++ msvcrt.dll!77bffc5d() libeay32.dll!1003d861() libeay32.dll!1006a15a() libeay32.dll!1006a4d6() libeay32.dll!10068cf8() CryptoOpenSSLTest5.exe!main(int argc=1, char * * argv=0x003e5a40) Line 82 + 0xf C++ CryptoOpenSSLTest5.exe!mainCRTStartup() Line 398 + 0x11 C kernel32.dll!7c816d4f() ntdll.dll!7c925b4f() kernel32.dll!7c8399f3() ---------- snap ---------- That "CryptoOpenSSLTest5.exe!main [...] Line 82" is the call of PEM_read_RSAPrivateKey.
