More debugger bugs

I know, but I wonder if at that time we will have a new gdb release and 
if that release will be available for the common distributions and 
platforms KDevelop is running.

This is what I meant with --enable-debug without full. I found the whole 
flag line used to compile:

CXXFLAGS 
= -Wno-long-long -Wundef -ansi -D_XOPEN_SOURCE=500 -D_BSD_SOURCE -Wcast-align
 -Wconversion -Wchar-subscripts -Wall -W -Wpointer-arith -fno-builtin -g -O2 
-fno-schedule-insns -fno-inline -pipe -Wformat-security -Wmissing-format-attribute 
-Wno-non-virtual-dtor -fno-reorder-blocks -fno-exceptions -fno-check-new -fno-common 
-DQT_CLEAN_NAMESPACE -DQT_NO_ASCII_CAST -DQT_NO_STL -DQT_NO_COMPAT
 -DQT_NO_TRANSLATION


I checked and --enable-debug=full gives us:
CXXFLAGS 
= -Wno-long-long -Wundef -ansi -D_XOPEN_SOURCE=500 -D_BSD_SOURCE -Wcast-align 
-Wconversion -Wchar-subscripts -Wall -W -Wpointer-arith -fno-builtin -g3 -fno-inline -pipe 
-Wformat-security -Wmissing-format-attribute -Wno-non-virtual-dtor -fno-exceptions -fno-check-new -fno-common 
-DQT_CLEAN_NAMESPACE -DQT_NO_ASCII_CAST -DQT_NO_STL -DQT_NO_COMPAT -DQT_NO_TRANSLATION

So -O2, -fno-schedule-insns is missing.

Sure. If your distribution doesn't have it, check out from the KDE SVN
(/home/kde/trunk/kdenonbeta/unsermake), create a link to the unsermake 
executable into /usr/local/bin .

Run unsermake -f Makefile.cvs for KDevelop and later instead of make 
always use makeobj.

Be sure to not mix automake and unsermake builds (so clean your build 
dir before switching or use different build dirs for them).

Now what's interesting is that I cannot reproduce anymore the frame bug 
with the same code. :-( I will try to get you a 100% useful testcase.
