Hello, compiling sca module rises next warning: sca_call_info.c: In function ‘sca_call_info_update’: sca_call_info.c:1977:7: warning: the comparison will always evaluate as ‘true’ for the address of ‘call_info’ will never be NULL [-Waddress] sca_call_info.c:1984:14: warning: the comparison will always evaluate as ‘true’ for the address of ‘call_info’ will never be NULL [-Waddress] The lead to the next define, which does not seem right at first sight #define SCA_CALL_INFO_EMPTY( ci1 ) \ ((ci1) != NULL || \ ((ci1)->index == SCA_CALL_INFO_APPEARANCE_INDEX_ANY && \ (ci1)->state == SCA_APPEARANCE_STATE_UNKNOWN)) Either first condition has to be ==NULL or the || has to be relaplced by &&. Otherwise, if stays like now, if ci1==NULL, will result in a crash, by accessing ->index and ->state of a null pointer.
