Summary: Incorrect process return code with -fdump-core
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: libfortran
AssignedTo: [email protected]
ReportedBy: [email protected]
Consider the program
program errcode
stop 10
end program errcode
$ gfortran errcode.f90
$ ./a.out
STOP 10
$ echo $?
10
$ gfortran -fdump-core errcode.f90
$ ./a.out
STOP 10
Quit (core dumped)
$ echo $?
131
Looking at runtime/error.c (sys_exit) the reason is quite obvious; with
kill(getpid(), SIGQUIT);
the process kills itself (return code is 128 + signal number = 131 in this
case) and never gets a chance to execute exit() with the provided exit code!
