New issue 2945: Build with debug info and continuation support, got
"'no_collect' function can trigger collection" error
https://bitbucket.org/pypy/pypy/issues/2945/build-with-debug-info-and-continuation
Yuxuan “fishy” Wang:
I was trying to build pypy3.5 (from tag `release-pypy3.5-v6.0.0`) with debug
info (`-O0`) and continuation support (because that's required by greenlet),
this is the command line I used for building:
```
pypy ../../rpython/bin/rpython -O0 --continuation --gc incminimark
targetpypystandalone --withmod-_continuation
```
But I got this error after 99%:
```
