Re^2: Tracking down the source of a new 5.10 warning

Ok, I've tracked down the problem to Regexp::Common. I've changed places in the code that used to have:

use Regexp::Common;
[download]

to instead

use Regexp::Common qw(number);
[download]

Which should actually reduce memory usage as well. And the reason that my Carp/$SIG{__WARN__} trick didn't work was because this was a place in the test suite that generated code and executed it in another process (with a fresh new perl). Thanks for all the suggestions.

Ah. If you'd wanted to affect another perl, you could use the environment variable PERL5OPT. I've occasionally run with it set to things like `-MCarp::Always` to convert all my programs to use verbose warnings.1 ⠤⠤ ⠙⠊⠕⠞⠁⠇⠑⠧⠊	[reply] [d/l]
