Not really ... there's no plausible reason to crash there, either. Just for entertainment's sake, try recompiling with -O0 instead of the default -O2. (Rather than trying to browbeat configure into doing this, I'd suggest manually adjusting CFLAGS in src/Makefile.global, then "make clean" and rebuild.) This has two purposes: if it's a compiler bug, that will likely make it go away; and if gdb is misleading us about exactly where the crash is, that should help it give a correct answer. regards, tom lane
