And then the perl library (Imagemagick.pm?) which loads the imagemagick.so segfaulted. <tschwinge> ImageMagick did this change in the middle of a x.x.x.something release.. <tschwinge> My next step would have been to test whether libgomp works at all for us. <youpi> ./usr/sbin/debootstrap:DEBOOTSTRAP_CHECKSUM_FIELD="SHA$SHA_SIZE" <youpi> erf <youpi> so they switched to another checksum <youpi> but we don't have that one on all of our packages :) <youpi> tschwinge: <youpi> buildd@bach:~$ OMP_NUM_THREADS=2 ./test <youpi> I'm 0x1 <youpi> I'm 0x3 <youpi> libgomp works at least a bit <tschwinge> OK. <pinotree> i guess we should hope the working bits don't stop at that point ;) <tschwinge> If open_issues/perlmagick is to be believed a diff of 6.4.1-1 and 6.4.1-2 should tell what exactly was changed. <tschwinge> Oh! <tschwinge> I even have it on the page already! ;-) <tschwinge> -fopenmp <youpi> I've tried the pragmas that imagemagick uses <youpi> they work <tschwinge> Might be the issue fixed itself? <youpi> I don't know, it's the latest libc here <youpi> (and latest hurd, to be uploaded) # Other [[!debbug 551017]] Code in Svn: `+ 1` missing to account for both `/` and `\0`.
