please ignore previous post.
gcc passes params in the right way but something is wrong.

with the original sourcecode gdb shows stack frame with
invalid parameters (name, xmluiFile):

#4  0x4008b10c in KonqMainWindow (this=0x812afc0, initialURL=@0xbfffef5c,
    openInitialURL=false, name=0x2e <Address 0x2e out of bounds>,
    xmluiFile=@0x2e) at konq_mainwindow.cc:218

if I access xmluiFile at the begin of this cstr, eg.
qDebug("name=%p, xmlui=%s", name, xmluiFile.ascii());
gdb will show a stack frame with correct params:

#4  0x4008b130 in KonqMainWindow (this=0x812afc0, initialURL=@0xbfffef5c,
    openInitialURL=false, name=0x0, xmluiFile=@0xbfffef1c)
    at konq_mainwindow.cc:218

disassembler shows only s/eax/edx/ in several places.
is this a gdb-6.3 bug?
i give up.
