Most likely your compiler will already put them in the bss. Various programs will rely on the bss to be set to 0, so I suggest you do that.

Inside the file obj_xref.c, there is a variable sigx_app that never be initialize, so this variable sigx_app will be changed anytime. The uninitialized variable sigx_app will cause the system crash at anytime. Could you please tell me the reason why the variable didn’t initialize? The variable sigx_app is a global variable. If your global variables are not being initialised then I would classify this as a compiler bug. OpenSSL assumes a compiler to be conformant with the C90 spec. All global variables have static storage duration. From section 6.5.7 of C90: If an object that has static storage duration is not initialized explicitly, it is initialized implicitly as if every member that has arithmetic type were assigned 0 and every member that has pointer type were assigned a null pointer constant.

Hi, I am porting openssl_1.0.1g to our private OS. But we meet some problem, could you please give me a favor. The issue is described below. Inside the file obj_xref.c, there is a variable sigx_app that never be initialize, so this variable sigx_app will be changed anytime. The uninitialized variable sigx_app will cause the system crash at anytime. Could you please tell me the reason why the variable didn’t initialize? l The code we modified below will fix the issue at our OS, could you give us some suggession. Origin : STACK_OF(nid_triple) *sig_app, *sigx_app; Modified : STACK_OF(nid_triple) *sig_app = NULL, *sigx_app = NULL; Best regards. ___ openssl-dev mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-dev
