New Revision: 35920
Changeset: http://dev.haiku-os.org/changeset/35920/haiku
Modified:
haiku/trunk/src/system/kernel/debug/debug.cpp
Log:
kernel_debugger_loop(): We need to use a dedicated jmp_buf for the call of
arch_debug_stack_trace() through debug_call_with_fault_handler(), since the
one in the CPU structure can only be used for debug_{strl,mem}cpy(), which do
not potentially have nested debug_call_with_fault_handler() calls.
