netbsd-11 "ag" coredump after mmap()
Upgraded a few machines to netbsd-11 and rebuilt all packages, and
everything seems to work apart from a couple of packages which do not
build, and "ag" now dumping core in a few cases
(That is pkgsrc/textproc/the_silver_searcher)
Noticed when running against a checked out copy of netbsd-11 source
(which seems quite apt).
% ag bob crypto/external/bsd/netpgp/dist/src/netpgpverify
crypto/external/bsd/netpgp/dist/src/netpgpverify/Makefile
zsh: segmentation fault ag bob crypto/external/bsd/netpgp/dist/src/netpgpverify
Turns out it is choking when trying to check
crypto/external/bsd/netpgp/dist/src/netpgpverify/digest-20121220.tgz
and a tail end of ktrace shows a SEGV after mapping a file
11770 11770 ag NAMI

11770 11770 ag CALL madvise(0x73c382be7000,0xb602,2)
11770 11770 ag RET madvise 0
11770 11770 ag PSIG SIGSEGV SIG_DFL: code=SEGV_MAPERR,
addr=0x73c382e28f96, trap=6)
Does anyone know offhand of anything that might have changed in this
area since -10?
Thanks
David
