 Some further experimenting with a test program (I use
 https://gitlab.com/Rhialto/macro11; it has sanitizer options commented
 out in the Makefile) shows that the base compiler from NetBSD/amd64 9.3
 (gcc version 7.5.0 (nb4 20200810)) works fine. It doesn't require me to
 disable ASLR with paxctl. It also detects the memory leak in
 __cxa_atexit_internal.
 
 lang/gcc8 and lang/gcc10 (with the patches from this PR) seem to work
 about equally well, which is to say they don't work but fail with
 
 ==19445==ASan runtime does not come first in initial library list; you          
 should either link runtime to your application or manually preload it           
 with LD_PRELOAD.                                                                
 
 and following the suggestion about LD_PRELOAD doesn't help.
 -lasan is definitely linked, just not first.
