Build error using gcc/g++12 #27

I tried to build IPCL with gcc-toolset-12 and build failed with the following error message. However, there is no build failure with gcc8.5.

Hi this is a known bug introduced in IPP-Crypto with gcc-11 and higher, due to the stringop-overflow false positive error. We applied a emergency patch 250ab34ced7bd8aab7f41e57e3f2a52dbc51c1b4, where it adds -Wno-stringop-overflow compiler flag when using GNU compilers. It can be found in the upstream branches as well as v1.1.4 release tag with the updates.
