Something weird is going on. Once I have a shell open, and fire up a second level bash (non-login), Ctrl-C behaves correctly and cancels the current line input with exiting the shell. But then when I type exit, bash returns with exit status 1, even though it did absolutely nothing and should be returning 0. (On a possibly related note, in ksh, typing Ctrl-C then exiting gives exit status 130, instead of 0; but zsh gets it correct and returns 0). But in the login shell, Ctrl-C is killing bash rather than being intercepted. I don't recall changing anything between the -8 and -9 release that would affect only login shells, but I do know that only -9 uses spawnve(), so maybe there are some corner case bugs in spawnve() behavior (or bash's new use of it) that get tickled by login shells. The patch in -9 only attempts to use spawnve when bash is not worried about job control. For regular shells job control is on by default, but for login shells, I noticed with an strace that job control is not enabled until after /etc/profile (and so forth) have completed execution, so login shells are invoking spawnve during startup. As a workaround, if you want to play with bash-3.0-9, either use it as a non-login shell or don't hit Ctrl-C. I'm also having no problems whatsoever with tilde-expansion using bash-3.0-9 on my XP or win98 machines; it was only on a Win2k box where that didn't seem to work (I'll have to check that again). - -- Life is short - so eat dessert first!
