#244 unicon -c stressCo : compile err unless -fa

[Charles Evans]

see test program stressCo.icn in bug [#242]
It does no string-invoke, but
without -fa, it fails to compile:

$UNICON -C stressCo

This reproduces for me. It is likely that the compiler determines that a, b, and c are never activated, so A(), B(), and C() are never called, so it is omitting the code for them, but obviously it is not omitting the create code, which contains links to them, so this is a bug. Thanks for the -fs workaround observation.

trivia:
in tests/coexpr:
unicon -C cobench
./cobench
# ^ works.

[Charles Evans]

Works now after [r5274], thanks for the fix. Ok to close this.

[Charles Evans]

Or maybe: new title:
unicon -C -nofs stressCo # fails

[Charles Evans]

Also, for completeness, naturally
iconc stressCo
# ^ fails
iconc -fa stressCo
# ^ works

[Charles Evans]

snapshot 9/6:
iconc stressCo
now works.
Ok to close this.
