Following sample Kconfig generated a segfault:
config FOO
bool
select PERF_EVENTS if HAVE_HW_BREAKPOINT
config PERF_EVENTS
bool
config HAVE_HW_BREAKPOINT
bool
depends on PERF_EVENTS
Fix by reverting back to a valid property if there was no
property on the stack of symbols.
The above pattern were seen in sh Kconfig.
A fix for the Kconfig file has been sent to the sh folks.
