User-Agent: Build Identifier: quik (1-29-02 sync) compiles with gcc3.2.1 now but is non-functional. It overwrites functioning bootblock while emerging/installing to ext2 /boot partition. It segfaults when run. Reproducible: Always Steps to Reproduce: 1. emerge quik 2. run quik 3. restore from backups 4. repeat Actual Results: machine failed to load kernel - hangs in OF Expected Results: load kernel, exec init debian quik sources compiled with 2.95.3 function correctly see bugs 14655 8093
can you run: gdb quik and at the gdb prompt, type: run <any quik arguments here> this should result in a SIGSEGV (a segfault). at this point, at the gdb prompt, type: where and post the output here. sorry, but i don't have an oldworld machine to try this out on

Hey, whenever you need testing of this, I'm standing by with my trusty 9600/200, I'm fairly comfortable with OF and quik (I used to run it before gcc 3.x). Mail me, catch me on irc, whatever.
listbox: the command to run at the second gdb prompt is 'where' not 'run'. thanks!

can both of you guys emerge rsync and make sure you have: gcc-3.2.1 glibc-2.3.1-r2 binutils-2.13.90.0.18 recompile and see if you get the same behavior. from what i and vladimir figured out on IRC, it's choking during the exit(0) call, which implies (to me) some compiler/assembler/linker mismatch. let's try this and see what it does.
updated binutils-2.13.90.0.16 --> binutils-2.13.90.0.18 and received identical gdb output to prior comment
I got very similar output, too. Upgraded GCC (14 hours of compiling), glibc (quite a few, but no that many, and binutils, output is as follows: Starting program: /sbin/quik -v Second-stage loader is on /dev/sdb5 Config file is on partition 5 Writing first-stage QUIK boot block to /dev/sdb5 Making /dev/sdb5 bootable (map entry 5) Writing block table to boot block on /dev/sdb5 strnpy done finfo access done 2nd strncpy done returning from write_block_table() syncing done syncing (no debugging symbols found)...(no debugging symbols found)...

got a potential fix to vladimir. he's testing.
please try quik-2.0.1.0-r3 (it's marked ~ppc). there was a bug in the quik code where a missing fclose() was causing glibc's file syncing to SIGSEGV upon exit(). please report back if this works for you. i can confirm it no longer SIGSEGVs, but have no oldworld machine to try it on.
On this machine - Umax s900dp, OF 1.0.5 - quik compiles and executes without errors, but machine hangs in OF while trying to open scsi boot device with no output to OF console. Machine accepts no input after pointing OF at the correct partition - requires forced reboot.
resolved as non-functional
