New description:

 STR:

 1) Download 6.5a1-hardened
 2) Download the corresponding debug files and move `Debug` to
 `Browser/.debug`
 3) Start 6.5a1-hardened as usual and update
 4) After restart the browser window is visible shortly but then Tor
 Browser crashes with
 {{{
 ASAN:SIGSEGV
 =================================================================
 ==7246==ERROR: AddressSanitizer: SEGV on unknown address 0x000000000000
 (pc 0x7faa929b5d27 bp 0x7faa9bf89170 sp 0x7faa9bf89040 T4)
 SRAT init
 SRAT warning: cannot find Memory Layout File. Stack trace will be probably
 wrong.
 ASAN:SIGSEGV
 ==7246==AddressSanitizer: while reporting a bug found another one.
 Ignoring.
 }}}

 Starting again works and not moving the debug files into `Browser` +
 updating is fine, too.
