-g and no stripping (and -O0 -fno-omit-frame-pointer -fno-optimize-sibling-calls -fno-common) is suggested, but seems not to be sufficient.
(With gdb it works of course, but ASAN/UBSAN is much more comfortable :)
It became off-topic now for pkgsrc when base-gcc is the suggested way. I'll better put it on the netbsd-users list. Thank you!
