Display type: unknown
What were you trying to do?
Use the sun tool "ptime"
What's wrong:
ptime dumps core and doesn't print a warning message if it can't
exec a process. To repeat, run "/usr/proc/bin/ptime foo" when there
is no command "foo" in $PATH. A child process dumps core so there
isn't even a shell error message. (I discovered this trying to run
ptime on a shell alias -- the alias wasn't expanded because it wasn't
the first word of the command and the name of the alias wasn't a
program in $PATH.)
What should have happened:
ptime should have said "foo: No such file or directory". I used
a debugger on the core dump and it appeared to be attempting to
print an error message, but passed a NULL pointer for the filename
to print.
Please describe any relevant documentation references:
proc(1)
Do you have any other comments?
Yes. This is a Sun OS bug, not an MIT bug, so the bug report
should be forwarded to Sun.
