Bash Version: 5.0
Patch Level: 3
Release Status: release

Description:
After the below described construct, the line numbers are off, this affects 
both the envvar LINENO and the line numbers bash writes on an error.
 
It seems that the newlines in {} are ignored, if it is after "() ||" or "() &&" 
.

 

Also tested with `true || { ... }` and { ... } || { ... } . In those cases the 
correct line numbers are shown.

Repeat-By:
#!/bin/bash

( echo foo; ) || {<!-- -->
    echo bar    # 4.line
    echo bar    # 5.line
    }           # 6.line
echo lineno: $LINENO   # 7.line
[[ -e bla]]     # 8.line

output:

foo
lineno: 4
./tester.sh: line 5: unexpected EOF while looking for `]]'
./tester.sh: line 6: syntax error: unexpected end of file

 

=> The reported line-numbers are 2 lines off.
