I do see the problem of logging everything. But in your case I'm pretty sure that you have to see the whole process until the argument list is too long. I guess that there is some weired case of accumulation as I said before.

Anyway, IMHO you don't have to change the code of IPC::Run, as I'm sure you could catch the argument list this way (only an example):

my $gv = GraphViz2->new(%args); eval { $gv->run(); }; if(my $rc = $@) { print STDERR "argument string: " . $gv->dot_input . "\n"; confess $rc; }
I'm really curious whether you catch your bug. Perhaps you have the time to tell us.

Happy digging
