That sounds really useful, although I bet it assumes that the build
environment is the same on all machines. Or at least similar. I'll have

Obscure bug of 2004: BASH BUFFER OVERFLOW - if bash is being run by a
normal user and is setuid root, with the "vi" line edit mode selected,
and the character set is "big5," an off-by-one errors occurs during
wildcard (glob) expansion.
