This morning I installed the latest Tumbleweed updates on my laptop. The result is that Thunderbird and Chromium are broken. What I see is
the following: Checking upstream it seems that this crash in blink was already reported as a GCC6 regression and that there is also actually a crash in V8 when compiled with GCC6.
All are related to the same problem, which is described in an article on stackoverflow as:
"Value range propagation now assumes that the this pointer of C++ member functions is non-null. This eliminates common null pointer checks but also breaks some non-conforming code-bases (such as Qt-5, Chromium, KDevelop). As a temporary work-around -fno-delete-null-pointer-checks can be used. Wrong code can be identified by using -fsanitize=undefined."
The same issue appeared with the KDE Screenlocker which caused the issue noticed in openQA with this snapshot. So Qt5 has been resolved. I will make the same adjustment to Chromium and submit it to Factory/Tumbleweed.
My feeling is that Thunderbird is suffering from the same and should also be build with the temporary work-around.
