--- Comment #27 from Daniel Black ---
reduced test case, quite similar however just to be sure:
int a, b;
__attribute__((__cold__)) fn1();
__attribute__((always_inline)) fn2() { fn1(); }
fn3() {
fn2();
if (b)
a = 0;
}
[Bug c++/80593] [7 Regression] GCC 7, aligned_storage and “dereferencing type-punned pointer will break strict-aliasing rules”
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80593 Daniel Black changed: What|Removed |Added CC||daniel.black at au dot ibm.com --- Comment #10 from Daniel Black --- FYI I have tested from the gcc master (x86_64-pc-linux-gnu-g++ (GCC) 8.0.0 20170605 (experimental)) and it doesn't identify the the following bit of rocksdb code as a warning where previously it did. So fixed for me on master. ./db/write_thread.h:227:78: error: dereferencing type-punned pointer will break strict-aliasing rules [-Werror=strict-aliasing] return *static_cast(static_cast(&state_mutex_bytes)); ref: https://github.com/facebook/rocksdb/issues/2382 Still fails using the gcc at the head of the gcc-7-branch however
