Category:	MySQL Server: mysqlpump Command-line Client	Severity:	S3 (Non-critical)
Version:	8.0.27, 5.7.36	OS:	Any
Assigned to:		CPU Architecture:	Any
Tags:	regression

Description:
Crashing mysqlpump if used with -p flag expecting to solicit a password in the tty.

[root@test ~]# mysqlpump -p
terminate called after throwing an instance of 'std::logic_error'
  what():  basic_string::_M_construct null not valid
Aborted (core dumped)

This works:
[root@test ~]# mysqlpump -ubkp -phello -hlocalhost > test
mysqlpump: [Warning] Using a password on the command line interface can be insecure.
Dump progress: 1/1 tables, 0/0 rows
Dump completed in 154

How to repeat:
Install mysqlpump utility and run mysqlpump -p from the terminal.

Forgot to mention that I was testing this on CentOS 8 but I'm not sure if that really mattered or not.

Hello Jericho,

Thank you for the report and test case.
Verified as described.

regards,
Umesh
