Bug ID: 87969
Summary: -fcheck does not raise signal
Product: gcc
Version: 8.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: maik.riechert at arcor dot de
Target Milestone: ---
When compiling code with -fcheck=.. I expect that a failing runtime check would
raise a signal so that gdb stops at that point, however this is not the case
and the program just exits after printing the runtime check message.
Example program:
program main
implicit none
real, dimension(5) :: arr
arr(10) = 42.
end program
Compiled with "gfortran -g -fcheck=bounds main.F90" and run under gdb:
(gdb) run
Starting program: /.../a.out
At line 4 of file main.F90
Fortran runtime error: Index '10' of dimension 1 of array 'arr' above upper
bound of 5
Error termination. Backtrace:
