#1686: Null PMC access in find_method('signature') using Digest/MD5 from rakudo
-----------------------------------+----------------------------------------
Reporter: cosimo | Type: bug
Status: new | Priority: normal
Milestone: | Component: none
Version: 2.5.0 | Severity: medium
Keywords: find_method signature | Lang: perl6
Patch: | Platform: linux
-----------------------------------+----------------------------------------
Comment(by cosimo):
Just to not forget about it, the `find_method('signature')` problem goes
away by replacing:
{{{
pir::load_bytecode('Digest/MD5.pbc');
}}}
with:
{{{
pir::load_bytecode('Digest/MD5.pir');
}}}
Then the error message becomes `Null PMC access in invoke()`, for which,
because of #1694, you need to apply the following patch:
{{{

}}}
The only remaining problem was that the code didn't "box" the returning
string pmc. So I had to replace:
{{{
%r = $S0
}}}
with:
{{{
%r = box $S0
}}}
