I am using 7.99.36 though. I've had a lot of trouble installing fonts/fontforge specifically, so I experimented with it, deleting work/.install_done when I got through instlal by mistake, to save on build time.
with help debugging, I found that it will not occur if security.pax.aslr.flags=0x1 (disables PAX_ASLR_STACK). then used flags=0x1e to reduce the noise (flags which do not cause it) and turned on debug to see the values used before segfault occurs. then flags=0x3e and setting fixed rand value as before the segfault also causes segfault. I see if I set the last two numbers to anything but 0x ... 00 it will segfault (e.g. security.pax.aslr.rand=0x00000001 and flags=0x3e). I'm not sure how anything got through with these odds.
