EVP_DigestInit_ex will crash on Linux

[Frank Büttner]

Hello again my app run fine on windows, but crash on Linux at the call
of EVP_DigestInit_ex(&Hash,EVP_sha256(),NULL)
any special on Linux?
gdb tell me:
#0  0x4124a26d in engine_unlocked_finish () from /lib/libcrypto.so.6
#1  0x4124a3bb in ENGINE_finish () from /lib/libcrypto.so.6
#2  0x4125febe in EVP_DigestInit_ex () from /lib/libcrypto.so.6
Some lines before EVP_DigestInit_ex() I call EVP_MD_CTX Hash;
Must I call some other thinks on Linux before?

Thanks
