Well, this is possible if one combines this patch with the ISO C Bindings of
our fortran-experiments branch. One could then simply use:
integer, parameter :: SIGBUS = 7
integer :: res
interface
function kill(pid, signal) bind(c, name='kill')
use :: ISO_C_BINDING
integer(C_INT),value :: pid, signal
integer(C_INT),bind(c) :: kill
end function kill
end interface
res = kill(0,SIGBUS)
To get a backtrace. Alternatively, with the current patch and the main branch,
one only needs to generate somehow SIGSEGV, SIGFPE, SIGILL or SIGBUS. For
instance as follows:
-ffpe-trap=zero -fbacktrace with
r = 0.0
r = 1.0/r
which gives a nice backtrace.
