Well, how about explicitly disabling a few debugging-unfriendly
options when we are compiling with -g? One particularly nasty option
can be removed with -fno-cross-jumping: without that, post-mortem
analysis of failed assertions becomes rather erratic (backtraces point
to nonsensical places). This has cost me a lot of grief once.
