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;
}

Also getting this on linux kernel 4.13 release on gcc master branch but not
gcc-7:

There are at least two locations that generate this backtrace.

gcc -O1 -c -o drivers/scsi/mpt3sas/.tmp_mpt3sas_scsih.o   ./mpt3sas_scsih.i

Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.

Simplest ICE generation is -O1. -O0 gets to code errors.

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<std::mutex*>(static_cast<void*>(_mutex_bytes));

Still fails using the gcc at the head of the gcc-7-branch however

32bit powerpc and powerpc64 builds are fixed. BE & LE.

Sorry the libgcc2.i source has been purged.

Thanks for the fix.
