Is this 8G of RAM? If yes - I'd be curious to know which part of
libsanitizer needs so much memory.


Here is what I have in gcc.log:
==12356==ERROR: AddressSanitizer failed to allocate 0x200001000
(8589938688) bytes at address ffffff000 (errno: 12)^M
==12356==ReserveShadowMemoryRange failed while trying to map
0x200001000 bytes. Perhaps you're using ulimit -v^M

Interesting. AFAIK Asan maps shadow memory with NORESERVE flag so itshould not consume any RAM at all...

-Y
