I attempted to reproduce the issue using host : ubuntu 22.04 which has gcc-11.2.0 but i don't see the same error. I am using : 101bca9 (HEAD -> master, origin/master, origin/HEAD) Add vcpkg installation instructions (#200) I see: yasm-3857-expand_mmac_params-null-pointer-deref:1540: error: label or instruction expected at start of line ================================================================= Direct leak of 4100 byte(s) in 4 object(s) allocated from: Direct leak of 4100 byte(s) in 4 object(s) allocated from: SUMMARY: AddressSanitizer: 8200 byte(s) leaked in 8 allocation(s). This is not same error as reported in this bug I am able to spend some time to resolve some Yasm CVEs but I would need some guidance . |
System info:
Ubuntu 16.04.6 LTS, X64, gcc 5.4.0, yasm (latest master 009450c)
