Bugzilla Bug 102519

flux won't run. sorry, i can't BE more descriptive... it just won't run. at
all.
for any reason. when it is executed, it just dies...

i have not recently upgraded/change/merged x11, flux, or any other relevent
package. i have not changed the config files. i have not done anything which i
can guess would fux0r things

x11 works fine, as do other WMs. this problem occurs on two of my boxes:

also, i think there is a post on the forums about this problem as well:

as you can see, the logs are less than helpful

I've the same problem.

Interestingly enough, 0.9.9 doesn't share this problem. It seems to work just
fine...

0.9.11 works for me, but 0.9.12+ is broken. this is strange, b/c i've been
using
>0.9.12 for many months

strace?

flux_strace.log

strace of the entire x session

same problem here.
i tracked it down to the latest imlib2 upgrade(1.2.0.007-r1).
downgrading imlib2 back to 1.2.0.007 and fluxbox works again.

The only change in imlib2-1.2.0.007-r1 is an imlib2-PIC.patch, so I guess some
of the assembly rework done there must be wrong.

fluxbox_strace.log

because the strace log attached in c#7 is only from startx

(uhm and sry for double post)

there is a small typo in the imlib2-PIC.patch.
at line 574
-       movq m_rb, %mm5
-       movq m_g6, %mm6
+       LOAD_IMMQ(m_rb, %mm5)
+       LOAD_IMMQ(m_g6, %mm6)
+       CLEANUP_IMMQ_LOADS(1)
                          ^^^
                doesnt clear the stack completly, no wonder that it segfaults ;)
replace last line with:
+       CLEANUP_IMMQ_LOADS(2)
and everything is fine.

vapier/spanky: take a look?

thanks Peter, that is indeed wrong

fixed in portage and in upstream
