Dear colleagues,

Segmentation fault (core dumped)
deleting files from sup/cvsroot-all/ did not help
unfortunately, quick usual `make -DDEBUG_FLAGS=-g' in
/usr/src/usr.bin/csup does not work, and I did not dig into this
deeply yet, so trace are without parameters:
This won't work. You need to do: make DEBUG_FLAGS=-g3 -ggdb -O0
The important part is not using -D. make.conf variables aren't
exported into the compiler environment (I'm not phrasing this
eloquently because I don't know how to describe it). The rest of the
gcc arguments I provided are highly recommended (especially -O0,
otherwise you probably won't get access to any variable data).
I can confirm this works, by the way. Look closely at the cc line
(past the initial -O2 -pipe -march=nocona).
cc -O2 -pipe -march=nocona -I.
-I/usr/src/usr.bin/csup/../../contrib/csup -DHAVE_FFLAGS -DNDEBUG
-ggdb -g3 -O0 -std=gnu99 -fstack-protector -Wsystem-headers -Werror
-Wno-pointer-sign -c
/usr/src/usr.bin/csup/../../contrib/csup/updater.c
Not being picky but just wanted to let you know that the flags specified
to DEBUG_FLAGS that you have listed above are perfectly fine but for
those without the knowledge of how this is done, the last flag specified
is usually the flag that wins.
So for DEBUG_FLAGS=-g3 -ggdb -O0 the -ggdb flag would be the debugging
type of ELF binary produced making the '-g3' flag just redundant.
Now in case you wanted the effect of '-g3' and '-ggdb' you can specify
'-ggdb3' instead.
As for the compile that was listed above it seems as if the flags were
reorganized in some way leading to '-g3' ultimately taking the cake.
Irregardless you will still end up with a binary that can be debugged by
gdb(1)/kgdb(1) either way.
Attached is a script that I use after buildworld installworld to rebuild
libthr and libc that is helpful for debugging that you may or may not
find useful.
