Re^3: perl built with -DDEBUGGING causes "failed to extend arg stack" error with XS modules by syphilis (Archbishop) on Jul 25, 2021 at 15:12 UTC
I recently built perl 5.32.1 with -DDEBUGGING You built that -DDEBUGGING perl yourself ?? I took one look at the "config_args" as reported in the "perl -V" output you provided in your original post and decided that this must be a perl provided by FreeBSD Ports. When I build perl on FreeBSD 12.0, I specify Configure args of "-des -Duse64bitall -Dprefix=/home/me/perl-5.x.y", and that's all. If I wanted a DEBUG perl then I'd just be adding the "-DDEBUGGING" flag to the list I used. (It's a while since I've built a -DDEBUGGING perl, so correct me if there are other flags that need to be added.) Try building your perl with a trimmed back list of configure args (like the list that I use) and see if that makes a difference. How did you actually build and install DateTime-1.54 from source ? (Seeing the output from that process might be useful.) Cheers, Rob	[reply]
Re^4: perl built with -DDEBUGGING causes "failed to extend arg stack" error with XS modules by parv (Parson) on Jul 25, 2021 at 16:15 UTC
Yes, I had built perl from source with debugging via Potrs (set `DEBUG` option for the port either in `/etc/make.conf` or via "dialog" brought up with `make config` in the port directory); at the end of "perl -V" ... `... Characteristics of this binary (from libperl): Compile-time options: DEBUGGING HAS_TIMES MULTIPLICITY PERLIO_LAYERS PERL_COPY_ON_WRITE ...` [download] I had rebuilt DateTime again (from source, with perl with debugging) in case I might not have removed all of its dependencies. No difference. I will try later to build perl & DateTime outside of Ports, but does not look like that would help any given the evidence so far.	[reply] [d/l] [select]
