+ <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

+ <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
