A quick debugging seems to show the problem is on the libpng side. Rebuilding it makes the problem disappear. It looks like it is due to the same issue we are doing this transition, ie the libpng structure expose a jmp_buf structure. I don't really now what to do... -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurelien@aurel32.net http://www.aurel32.net

So I guess the CPAN RT ticket can be closed, this is not a problem in Imager but some nice mess we have in Debian :/ Sorry for the noise, Tony. Cheers, gregor -- .''`.

Thanks, I'll admit I couldn't see any way to resolve this from my end - only tests changed in Imager's PNG code between 0.98 and 0.99. Closing. Tony
