For some reason, the compile time flag '-mcpu=k6' used with gcc 2.95.1
seems to generate broken binaries. Before I had pgcc 1.1.3 installed and
had always compiled all the kde packages with '-O6 -mcpu=k6'. This always
worked. Once '-mcpu=k6' removed, kppp recompiled only with '-O2' works as
usual.

I ran kppp from gdb, and found that kppp got segfault when I clicked on
'Deatils' button. Below is the output from gdb:

Program received signal SIGSEGV, Segmentation fault.
0x402622cb in QWidget::show () from /usr/local/qt/lib/libqt.so.1

I had recompiled Qt-1.44 with gcc 2.95.1

I will try again to compile kppp with '-O6 -mcpu=k6' flags, when the pgcc
2.95.1 patch will be out.


Thank you.
