After upgrading to qtcreator 4.0 loading simple qbs project crashes both qbs and qtcreator.

I've already sent an upstream bug report, not sure if it's an arch linux issue or not:
https://bugreports.qt.io/browse/QBS-974
This task depends upon

same problem,

maybe a gcc 6.x issue,

it would be interesting to build qtcreator with clang instead of gcc, in order to see if the bug is still here

Same problem When trying to open any QBS C++ projects created on Qt Creator 3.6, qtcreator crashs with segmentation fault. It happens when creating new qbs project too. Only happened after qtcreator-4.0.0 upgrade from qtcreator-3.6.1 in archlinux. Clearing user data doesnt solve the problem. Downgrading to qtcreator-3.6.1 solves the problem.

Upgrades:
upgraded qtcreator (3.6.1-2 -> 4.0.0-1)

Other updates that might be relevant:
upgraded llvm (3.7.1-1 -> 3.8.0-1)
   qtcreator.log (149.3 KiB)

Sounds a lot like a gcc specific problem with the qtcreator release build. Not sure whether it's a qtcreator bug where qtcreator unknowingly relies on undefined behavior or a gcc bug.

I was trying a few things and found out that qtcreator-3.6.1-3 (i missed it, going from 3.6.1-2 -> 4.0.0-1) crashs the same way as 4.0.0-1 with a segmentation fault when loading qbs projects. Maybe it was built with gcc6 too.

qtcreator-4.0.1 solved the problem.
