Compiler crashes trying to compile Aporia

[gradha]

Trying to compile Aporia version dom96/Aporia@6d6d172 with the compiler version c9326dc crashes with:

This seems to be an evolution of #326.

[gradha]

For the record, the first Aporia commit which crashes the nimrod compiler is dom96/Aporia@76412ac. OTOH, the previous Aporia commit doesn't compile due to TExecThrEvent lacking a p field which is part of a variant object defined in utils.nim, and that seems as it should compile, so maybe the crash is related to nimrod incorrectly processing that part of the code.

With the recent version the error messages and stack traces are slightly different:

This is odd because the declaration is an iterator. Is the AST semantic checking not seeing inside an iterator?

Here's some macosx C generated code for the compiler http://dl.dropbox.com/u/145894/t/compiler_nimcache_a3163de754aa9115e372e3338a7ea19bbdc23c5b.zip

An update on the issue. At http://pastebin.com/9J4UGcqk there's a log of me trying to compile Aporia with the devel branch using a debug version of the compiler. Notice how the first attempt crashes in the gc, the others where usual. But this seemed to be a one time attempt, now I am unable to replicate the gc stacktrace.

Also did notice babel doesn't crash now, and that's because it uses -d:release. The result for that is:

Users/gradha/project/nimrod/Aporia/processes.nim(329, 30) Info: instantiation from here
Users/gradha/project/nimrod/Aporia/processes.nim(300, 6) Error: identifier expected, but found '(event|event)'

Maybe that can throw ideas on what is different between debug and release modes.

[zah]

btw, Aporia can be compiled if you bootstrap with --gc:markAndSweep

./koch boot -d:release --gc:markAndSweep

[dom96]

From what other people are telling me this bug is now fixed. Can you confirm @gradha ?

[gradha]

babel install aporia works with 762e343.
