Good instinct. After spending a bit of time in the make sources, I found the code related to the segfault, which is file_exists_p(char *name), which splits up name into a dirname and a basename component, and tries to get the directory listing of dirname to check if basename exists in there. Funny, that this pointed me to another testcase: $ ls /dev/fd Segmentation fault $ ls /dev/fd/. Segmentation fault Haha. This could have been easier ;) Roland, is this enough info already to guess what is going on, or should I dig deeper into what happens in case /dev/fd/ is accessed as a directory and its listing is desired? I guess I can get lots of more info by following what happens in a normal ls in the client and in the magic translator. BTW, the segfault does happen after the code that searches for files in /dev/fd run, so there is some random corruption going on. Curiously, when I ran the original make command within gdb, it run successfully. Thanks, Marcus -- `Rhubarb is no Egyptian god.'
