Bugzilla Bug 105432

pif and pisum8 always result in a Segmentation fault after the output of pif
and
pisum8 reached 99%. pif /dev/hdd > pif-file result in data loses of the output
file, because of the Segmentation fault. Even as root.
jitterbeta and ta are working properly. Manual compiled pisum8 and pif is fully
working.

i cant guess, you need to post `emerge info` like the bug report page told you
to

Created an attachment (id=68080) [edit]
pxlinux-0.0.4-cleanups.patch

apply this patch and then rebuild with CXXFLAGS='-g -pipe' FEATURES=nostrip ...
then run `gdb --args pif /dev/dvd` and when it crashes, type 'bt' and post that
output here please

This works fine, thank you.

oh, so the attached patch fixes your segfault ?

Yes, and also this ugly messages disappear:

ah, very cool ... i thought the segfaults were from something else :)

0.0.4-r1 now in portage
