Bug 30381 – [Qt] Using QWebView crashes the application on FreeBSD

• Status: RESOLVED
• Resolution: REMIND
• Component: Text

[Bernhard Rosenkraenzer]

Running a QWebView based application (it runs fine on Linux) on FreeBSD 8.0 with Qt 4.6.0-beta (using the QtWebKit that comes with it) results in a crash with the following backtrace:

#0  0x2a6bdde7 in kill () from /lib/libc.so.7
#1  0x2a6bdd46 in raise () from /lib/libc.so.7

#24 0x08063886 in main ()

(Akili inherits QApplication, StoreBrowser inherits QWidget and has a QWebView child)

[Bernhard Rosenkraenzer]

This is the output on the console when it crashes:

terminate called after throwing an instance of '__gnu_cxx::__concurrence_lock_error'
  what():  __gnu_cxx::__concurrence_lock_error

[Kent Hansen]

Does the issue persist with 4.6.0 final or a more recent patch release?

[Benjamin Poulain]

Closing since there is not any new info about this task.
Please comment if you experience the problem with WebKit trunk so I we reopen the task.
