I recently built perl 5.32.1 with -DDEBUGGING & DateTime 1.54 from source (Ports, FreeBSD 13-STABLE). Now use of DateTime results in "failed to extend arg stack" (a solution seems not likely any time soon, tagged as "low serverity) ...

# perl -MDateTime -e0

What good is -DDEBUGGING now if it XS modules cannot run.

Is there a way to have perl built with DEBUGGING and XS modules not fail?

In reply to perl built with -DDEBUGGING causes "failed to extend arg stack" error with XS modules by parv

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.


No such thing as a small change
