Hi Developer, I see a problem with Net::SSH2 on my Solaris server where it is saying Segmentation Fault and dumping cores when trying to use ->connect() method. Attaching the core for your reference. I am using Net::SSH2 v0.40 on perl, v5.8.9 built for sun4-solaris-thread-multi. Let me know if any additional information is required. -- Thanks, G. Ashok Kumar

Did you compile it against the latest versions of libssh2 and openssl? A copy of the perl script you used would be helpful as well. Show quoted text

A core in itself doesn't do me much good. If you compile a perl with -DDEBUGGING -Doptimize="-ggdb3", build Net::SSH2, then produce a core, then do: gdb --core=core --args /path/to/your/debug/perl script.pl then do a bt when you get the SEGV and give me the backtrace, that would be more useful. If the backtrace shows libssh2, you'll need to compile libssh2 with --enable-debug. Show quoted text

Once you install perlbrew and initialize it, here is the command to build a debugging perl: perlbrew install -n -j 10 perl-5.14.2 -D DEBUGGING -D optimize="-ggdb3" then to use it: perlbrew use perl-5.14.2 same for any other version.
