+ Breakpoints to set at the beginning of the execution
+ (each breakpoint demands its own -b option, e.g. -b foo -b bar)
+ -e, --environment-variable
+ Environment variables to be set with 'exec-wrapper env' in GDB
+ (each environment variable demands its own -e option, e.g.
+ -e FOO=foo -e BAR=bar)
+
+ The following options do not take arguments:
+
+ -i, --no-direct
+ Selects whether to pass the --direct flag to the program.
+ --direct is useful when debugging glibc test cases. It inhibits the
+ tests from forking and executing in a subprocess.
+ Default behaviour is to pass the --direct flag, except when the
+ program is run with user specified arguments using the "--" separator.
+ -s, --no-symbols-file
+ Do not tell GDB to load debug symbols from the program.
