aspell segfaults if it is compiled with -Os in CFLAGS on alpha. If aspell is compiled with -O2, everything works as expected. aspell seems to be very sensitive to CFLAGS (at least on alpha), see Bug #35238. Adding this to the ebuild in src_compile() fixed the problem: if [ "${ARCH}" == "alpha" ]; then replace-flags -Os -O2 fi The end of "strace aspell" output: open("/dev/urandom", O_RDONLY) = 3 read(3, "+Z\232u\344\230\237\217", 8) = 8 close(3) = 0 brk(0) = 0x12002e000 brk(0x120050000) = 0x120050000 --- SIGSEGV (Segmentation fault) @ 0 (0) --- +++ killed by SIGSEGV +++ Even when emerge'd with FEATURES="nostrip debug" USE="debug", running "gdb aspell" only produced this output after SIGSEGV: "Cannot access memory at address 0x21b90".

aspell-0.60.3 and aspell-0.60.4 both don't segfault when compiled with -Os. I did a diff between 0.50.5-r4 and 0.60.3 to try to figure out where the problem came from, but there were some massive changes (the diff for aspell.cpp alone is >3000 lines) and I don't know the aspell code well enough to find the problem.
Thanks fixed
