<pinotree> tschwinge: i'm not totally sure, but it seems the pie options
for gcc/ld are causing issues
<pinotree> namely, producing executables that sigsegv straight away
<tschwinge> pinotree: OK, I do remember some issues about these, too.
<tschwinge> Also for -pg.
<tschwinge> These have in common that they use different crt*.o files for
linking.
<tschwinge> Might well be there's some bugs there.
<pinotree> one way is to try the w3m debian build: the current build
configuration enables also pie, which in turns makes an helper executable
(mktable) sigsegv when invoked
<pinotree> if «,-pie» is appended to the DEB_BUILD_MAINT_OPTIONS variable
in debian/rules, pie is not added and the resulting mktable runs
correctly
## IRC, OFTC, #debian-hurd, 2012-11-09
<pinotree> youpi: ah, as i noted to tschwinge earlier, it seems -fPIE -pie
miscompile stuff
<youpi> uh
<pinotree> this causes the w3m build failure and (indirectly, due to elinks
built with -pie) aptitude
## IRC, freenode, #hurd, 2013-01-19
<gnu_srs> pinotree: I can confirm that -fPIE -pie fails and only -fPIE
works for mktable in w3m. Still have to check with elinks. What's up doc?
## [[!message-id "20130211040854.GN5926@type.youpi.perso.aquilenet.fr"]]
[[glibc]] `t/pie-sbrk` branch.
