[ID 20010327.005] error in combining of regular epressions
Message ID:

This is a bug report for perl from Hans@kolej.mff.cuni.cz,
generated with the help of perlbug 1.26 running under perl 5.00503.
Hello!
Line that mach
$separator = qr/\s*?\t\s*/x;
m{^ \s* # leading spaces
(\d+) # $1 number
$separator # (tabelator)
(\w+) # $2 word
\s* $}isox;
does not match this regular expression:
$separator = qr/\s*?\t\s*/;
m{^ \s* # leading spaces
(\d+) # $1 number
$separator # (tabelator)
(\w+) # $2 word
\s* $}isox;
The only change is in definition of $separator (extra syntax).
I am using standard perl distribution on Debian Linux Potato.
Best regards
Hans Ginzel
