SubjectSIGSEGV: Linux 2.4.0 and Konqueror 1.9.8 (from KDE 2.1 Beta 1)
Date
Hi,

Konqueror behaves really strange with the new kernel (compiled with 2.95.2 as
all my kernels for a very long time)

I have not seen this behaviour (to this extent) with earlier 2.4 kernels.

Included a strace... strange use of brk - or? [included /proc/pid/maps too]
It bugs out like this for other reasons as well. (not zdnet specific)

Note: read on it is not the icon stuff that is strange...

Computer: PPro 180, 96MB RAM
Swap [from dmesg] :
Adding Swap: 530136k swap-space (priority -1)
Adding Swap: 133048k swap-space (priority -2)

Linux version 2.4.0 (root@dox) (gcc version 2.95.2 19991024 (release)) #2 Fri
