https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94125 --- Comment #2 from Jakub Jelinek --- Seems it is the ldist pass, which fails to figure out that k[c+3] load in the loop might alias with the k[c+1] = 0; store and moves all the 3 stores into a memset after the loop.

[Bug preprocessor/94127] #pragma system_header marks unrelated files as system headers

[Bug preprocessor/94127] #pragma system_header marks unrelated files as system headers

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94127 --- Comment #3 from Jonathan Wakely --- Well it comes before the #include for sys2.h so affects that, but you're right it shouldn't affect a header that isn't being included by sys.h.
