| Subject: | Error profiling code which uses Math::Pari |
Read Tim's blog post and wanted to try this awesome new profiler. I ran it against my test
suite like:
$ PERL5OPT=-d:NYTProf prove test/t/
As it ran through my test suite I got the following two errors (and only these 2):
unknown entersub xs '_gmul' at /usr/local/lib/perl5/site_perl/5.8.8/mach/Math/Pari.pm line
994.
SV = PVMG(0x8060cf4) at 0x80b2964
REFCNT = 3
FLAGS = (GMG,SMG,READONLY,pPOK)
IV = 0
NV = 0
PV = 0xad62020 "_gmul"\0
CUR = 5
LEN = 128
MAGIC = 0x80b6b98
MG_VIRTUAL = &PL_vtbl_sv
MG_TYPE = PERL_MAGIC_sv(\0)
MG_OBJ = 0x80b2940
MG_LEN = 1
MG_PTR = 0x8050b84 "1"

I hoped I'd be ok, and ran the report program but got an error:
$ nytprofhtml
Generating report...
File format error: token 4 (''), line 476422 at
/usr/local/lib/perl5/site_perl/5.8.8/mach/Devel/NYTProf/Data.pm line 72.
I then tried running it against a single test file (which shouldn't be using Math::Pari), and
while I got no errors running the test I got a different error running the report generator:
$ nytprofhtml
Generating report...

Finally, perl & platform information
$ perl -V
