--- Comment #1 from moonlightsentinel at disroot.org ---
Seems to be a stack overflow in the optimizer:

(gdb) run test100k.d
Starting program: generated/linux/debug/64/dmd test100k.d

Program received signal SIGSEGV, Segmentation fault.
0x000000000850d7a7 in optelem(elem*, unsigned int) (e=0xa12eec0, goal=1)
