It said: libgcc/unwind-dw2-fde-dip.c:406:16: warning: assignment to ‘_Unwind_Ptr’ {aka ‘long unsigned int’} from ‘const unsigned char *’ makes integer from pointer without a cast [-Wint-conversion] Git blame says: 49310a9933 (Florian Weimer 2023-06-06 11:01:07 +0200 406) eh_frame = p + value; This warning might be worth fixing. I suspect a cast will do it. ^ permalink raw reply [flat|nested] 7+ messages in thread
