Building from source on openSUSE Tumbleweed, 64 bit Qt 5.10, lazarus 1.8.2 and Qt5 widget, I see an ACCESS VIOLATION error on startup.
The problem occurs both with 6.5.1 and 6.6.0.

See attached gdb backtrace.

    Problem still present in 6.7.0 built with lazarus 2.0.

    Are there plans to address this issue?

    Hello, Qt5 portable package is now available in 7.8.0 release (Qt5 Pascal binding libQt5Pas.so.1.2.6 is required)
    I've introduced a small Qt5-specific conditional compilation change on 7.8.0 as on Lazarus/FPC versions I was able to test, TListView (with at least a colum defied) changing the viewstyle to vsReport at runtime crashes reporting access violation.
