BUG-REPORT: GTK+ problems when compiled with optimizations >= -O

[Konrad Podloucky]

Hi folks!

gcc-2.95.2 seems to do some weird stuff with the gtkhpaned.c
file from GTK+-1.2.7 (the widget doesn't resize correctly, see
http://ostbahn.tssc.univie.ac.at/konrad/stuff/gtkhpaned.png ),
when compiling with an optimization level greater than 2.

My system is:
Debian potato/Alpha
gcc version 2.95.2 20000220 (debian package:gcc-2.95.2-7)
GNU assembler version 2.9.5 (alpha-linux) using BFD version
2.9.5.0.22

command line options:
gcc -v --save-temps -DHAVE_CONFIG_H -I. -I. -I..
-DG_LOG_DOMAIN=\"Gtk\" -DGTK_DISABLE_COMPAT_H
-DGTK_EXE_PREFIX=\"/usr/local\" -DGTK_DATA_PREFIX=\"/usr/local\"
-DGTK_SYSCONFDIR=\"/usr/local/etc\"
-DGTK_LOCALEDIR=\"/usr/local/share/locale\" -I..
-DGTK_NO_CHECK_CASTS -DUSE_XIM -I/usr/lib/glib/include
-D_REENTRANT -I/usr/X11R6/include -g -O2 -Wall -c gtkhpaned.c -o
gtkhpaned.o

output from '-v':

I've also appended the .i file, but I don't think it will help
you much, since the problem will be in the assembly code
produced (however I don't have the slightest idea about Alpha
assembly, so I won't be able to help debugging)

Bye,
        Konrad
