note philkime Here is a simple example showing that even Capture::Tiny doesn't work in this case on Windows. <code> #!/usr/bin/perl use Capture::Tiny 'capture'; use File::Temp qw(tempfile); use Inline C; my ($stdout, $stderr) = capture { test_err() }; print "|$stderr|\n"; __END__ __C__ void test_err() { (void)fprintf (stderr, "ERROR"); } </code> 929318 930947
