На basalt у меня не работает санитайзер в hasher:

$ cat test.c
int main() {}
$ cc test.c -O2 -fsanitize=address && ./a.out
==2140439==ERROR: AddressSanitizer failed to allocate 0xdfff0001000 
(15392894357504) bytes at address 2008fff7000 (errno: 12)
==2140439==ReserveShadowMemoryRange failed while trying to map 
0xdfff0001000 bytes. Perhaps you're using ulimit -v
Aborted

Какое-то время назад санитайзер работал.

Не в hasher ошибки нет, но может потому, что машину давно не обновляли, 
за это время в санитайзер сломался в сизифе.

"AddressSanitizer failed to allocate 0xdfff0001000" гуглится, но решений 
не нашел.

Мне надо для проверки rpm-build (4.0.4.195-alt1). На e2k поймал такую 
ошибку при сборке MAKEDEV:

free(): invalid pointer

Подозреваю что в rpm-build может быть выход за пределы буфера.

Но на e2k санитайзер сломался на rpm-build, но как-то по другому. 
Поэтому решил проверить на x86_64.
