Bug#602568: squeeze-di-beta1 installer: partman hang

[Jean-Christian de Rivaz <jc@eclis.ch>]

I now have a backtrace:

I can reproduce this with this command from the package build:

parted-2.3/build-udeb$ LD_LIBRARY_PATH=./libparted/.libs/ 
~/install-O2/sbin/parted /dev/sdb print


While analyzing the debian/rules I found this:

# Workaround/fix bug #442308
CFLAGS += -fgnu89-inline
UDEB_CFLAGS += -fgnu89-inline

This bug is tracked here:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=442308

This workaround is now obsolete as is was introduced 3 years ago for 
parted 1.8-7 and we now use parted 2.3-3 that compile just fine without 
this option. But unfortunately this is not the cause of my problem.


After a lot of test with different config.status file, I found this 
picture by testing only the build-udeb:

library fail with CFLAGS=' -Werror'
library fail with CFLAGS='-g  -Werror'
library good with CFLAGS='-g -O2  -Werror'
library good with CFLAGS='-O2  -Werror'

Something wrong without the -O2 optimization ? Seem incredible. But... I 
just want to check:

library good in build-deb with CFLAGS='-g -O2 -fgnu89-inline -Werror'
library good in build-udeb with CFLAGS='-O2 -fgnu89-inline -Werror'
library fail in build-deb with CFLAGS='-g -fgnu89-inline -Werror'
library fail in build-udeb with CFLAGS='-fgnu89-inline -Werror'

Ouch! It better to use the -O2 optimizer !


Ok, now at this stage I can give some facts:

1) The lib/partman/init.d/30parted script is unable to detect and report 
abnormal parted-server end.

2) The CFLAGS -fgnu89-inline option from the bug #442308 can be removed 
for the current version of parted-2.3-3

3) Something bad happen with the parted-2.3-3 code when the -O2 
optimization is not used.

Enough for me. Please, someone from Debian, give me some instruction of 
what action must be taken now. Should I open others bugs report for 1) 
and 2) ?
