Hi,
when genksyms is used on drivers/char/joystick/pcigame.c during "make dep" it segfaults. There isn't any joystick configuration in the kernel (it's a plain "make oldconfig" from a fresh kernel copy).
/tmp/linux-2.4.20/drivers/char/joystick$ gcc -Wall -O2 -I/tmp/linux-2.4.20/include -E -D__GENKSYMS__ pcigame.c| genksyms -p smp_ -k 2.4.20 Segmentation fault
$ genksyms -V genksyms version 2.4.25 ...
It looks like the segfault is caused by the following line from the gcc output above:
struct pcigame *((void *)0) { struct pcigame *pcigame; int i;
which evaluates from
struct pcigame *pcigame_attach(struct pci_dev *dev, int type) { struct pcigame *pcigame; int i;
pcigame_attach(a,b) is defined to NULL in include/linux/pci_gameport.h if CONFIG_INPUT_PCIGAME{,_MODULE} isn't set (which is the case here). Fixing this line makes genksyms work. Don't know who's at fault here but segfaulting doesn't look good...
