| Subject: | "malformed JSON string" errors when gcov2perl is ran for XS distributions |
When trying to run "cover -test" from any distribution that contains XS
code, gcov2perl fails with a "malformed JSON string", and the reports
aren't generated. The first version of Devel::Cover that shows this
issue is 0.75.
I've attached a simple XS distribution that replicates the problem.
Thanks.
Vincent Pit.
