I noticed when running Grantlee unit tests against Qt4.7 that they were segfaulting on exit if they used scriptable tags. After a debugging session I’d narrowed it down to just creating a QScriptEngine in a plugin will cause a crash. Qt4.6 didn’t show the same behavior, so I thought there would be no more for me to do.
The workaround is to build in support for QtScript template libraries directly into the grantlee_core library instead of loading it in a plugin, which is the behavior as of this release. Hopefully that’s a temporary workaround.
