      Hi Rusty,

Thanks for reviewing the patch. V2 is attached, see my comments below.

Indeed, it was inspired by talloc_stack.h ;-)

I moved the module and tests under can/tal/stack and added a LICENSE and _info.

Done.

Done. The macro is calling a tal_newframe_() function because I’d rather not make the module’s stack variable ‘public’.

Skipped this one. We can declare it later if we change our minds.

Thanks

      ccanlint: avoid segfault when module_builds' linking fails · bdb8d751
      Peter Barker authored 
      In the case that the objects built but linking failed, module_builds.c
called score_file_error with a NULL ccan_file object and 0 for line
number.

score_file_error assumed that the ccan_file object it is passed was
not-NULL when appending file errors to the score's aggregate error
string.  It attempted to dereference it to get "fullname".

score_error was factored out from score_file_error.  It takes a
"source" parameter, which is the file's full name (and possibly line
number) in the score_file_error case, and the ccan module name in the
case of link failure.
