Hi Peter, > Thanks for this patch.
A bit later I learned that it's not a gcc 15 bug, but invalid C code in CLISP, and gcc 15 is the first compiler that happens to make an optimization based on the assumption that the code is ISO C compliant in this regard. So, I was wrong to blame GCC. > However for Debian 14/Forky we are probably going to migrate to GCC 15, as > you can see at > https://bugs.debian.org/cgi-bin/pkgreport.cgi?tag=ftbfs-gcc-15;users=debian-...@lists.debian.org > we're not alone in this ;) The title ftbfs-gcc-15 is misleading. It should better be called "FTBFS due to GCC 15 or -Werror=implicit-function-declaration or -Werror=format-security". In particular -Wformat-security is known to complain about perfectly valid and safe code.
