Dart VM gives segmentation fault

[DartBot]

This issue was originally filed by @tomaskulich

---

extract the following file and run ./segfault.sh (or run test/segfault.dart)

segfaults on Archlinux (dart SDK 1.0.0.3 and 1.0.0.10) and Linux Mint (dart SDK 1.0.0.3)

this bug happens only when simultaneously using unittest and string interpolation (try to modify lib/src/change_set.dart by replacing print('$x') by print(x.toString()) and everything works fine).

finally, I'm sorry for submitting such a lot of code.

What steps will reproduce the problem?
1.
2.
3.

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Please provide any additional information below.

No problem about the "lot of code". A reproducible crash is worth a thousand descriptions of what you might have been doing :)

Thanks again for filing the bug!

The test works if --no-use-inlining or --optimization-counter-threshold=-1 (disables optimized code). The crash is caused because optimizing compiler keeps calling the function it is optimizing (StringBase.interpolate)
