Package: puredata Followup-For: Bug #690410 Recompiled puredata with the following 2 lines added to the top of debian/rules:
# Stop problems with puredata crashing due to buffer space issues? export DEB_BUILD_MAINT_OPTIONS=hardening=+format,-fortify,+stackprotector,+relro This turns off _FORTIFY_SOURCE. Puredata works with out problems with the PD 'patches' in my project. If you look at the back trace in the stack dump in the original bau report, it crashed in: pd(pd_typedmess+0x45b)[0x456fab] pd(outlet_anything+0x4a)[0x458eca] pd(pd_typedmess+0x1db)[0x456d2b] pd(binbuf_eval+0x90b)[0x4600fb] pd(outlet_list+0x4a)[0x458e3a] pd[0x455b5c] pd(outlet_float+0x3f)[0x458d0f] pd(outlet_bang+0x29)[0x458be9] pd(sched_tick+0x77)[0x463047] pd(m_mainloop+0x1e9)[0x463319] bang, float, list are basic puredata objects. binbuf_eval() is also one of the functions. It looks like puredata uses functions like strcat(), strcpy() in non-conventional ways with some kind of buffer. Turning off _FORTIFY_SOURCE looks like it needs to be done to ensure 100% functionality. Just patching one or two instances of the functions may not get all the problem points fixed as the puredata algorithms probably assume that the functions will copy/concatenate indefinitely throughout the whole code base. Talk to upstream before turning on _FORTIFY_SOURCE please.
