| |
Hi,
Sorry, no patch, just a bugreport. :)
I did a mistake in some Kconfig changes (locally) and got a segfault from conf:
#0 0x10005fe0 in sym_check_deps () #1 0x10005f40 in sym_check_expr_deps () #2 0x1000605c in sym_check_deps () #3 0x1000f3f4 in conf_parse () #4 0x10003824 in main ()
The way to reproduce is simple. I just added the equivalent of this to arch/powerpc/Kconfig:
--- config TEST1 bool depends on TEST2 && PCI select TEST2
config TEST2 bool ---
Neither TEST1 nor TEST2 exists in the existing .config when I run make oldconfig to reproduce.
It's clearly invalid in that it depends on what it selects, but it should just abort instead.
