Re: perl segfaults when parsing script

No, I've not. In fact, I just tried it with both perl 5.005_03 and perl 5.6.1 on sun4-solaris, and could get no segfault:

<bioserv 117 [15:14] ~ >perl -e 'chop $x'
<bioserv 118 [15:14] ~ >perl -e 'chop FOO'
Can't modify constant item in chop at -e line 1, at EOF
Execution of -e aborted due to compilation errors.
<bioserv 119 [15:14] ~ >perl -e 'chop "BAR"'
Can't modify constant item in chop at -e line 1, at EOF
Execution of -e aborted due to compilation errors.
<bioserv 120 [15:14] ~ >perl -v

This is perl, version 5.005_03 built for sun4-solaris
[download]

(Similar results for 5.6.1 dropped)

Of course, I didn't have access to your program which segfaults perl. It could be helpful to give a minimal example which fails (= something I can try to run on my machine), as well as the output of "perl -V".

That's interesting.

Strange... "`perl -e 'chop foo'`" dumps core on "perl, v5.6.1 built for i686-linux", "perl, v5.6.1 built for IP27-irix", and "perl, v5.6.1 built for alpha-dec_osf" (except there it also manages to print an error message "Modification of a read-only value attempted." before it dies horribly). Not on "perl, v5.6.1 built for sun4-solaris", though. I've compared configs, and I can't find anything distinctively different that would cause sun4-solaris to survive. perlbug.	[reply] [d/l]
