Bug#999358: libwebkit2gtk-4.0-37: Upgrade from 2.30.1-1~bpo10+1 to 2.34.1-1~deb10u1 crashes evolution with "std::bad_alloc"

Dear Alberto,

I'm very sorry for filing the bug report. I think, it should be closed
for the following reason.

Actually there is no evolution/webkit/libjavascriptcoregtk crash if
only official debian packages are installed at the system.I made a big
mistake by installing a self compiled "gcc-10.2.0" at the machine
around one year ago. Along with others this "gcc*.deb" did install
"/usr/local/lib64/libstdc++.so.6" which "libjavascriptcoregtk" dyn-
links against. After removing my homebrewn "gcc-10.2.0" from the system
all runs fine, including "evolution".

*Excuse me please for my rookie like mistake. I should have known

Ah right, there are no debug packages for security updates... :-S

Ok, this is a bad allocation triggered by pathByAppendingComponent(),
it seems very unlikely that you run out of memory doing this
operation, maybe one of the parameters is corrupted... it would be
useful to see the rest of the backtrace.

The problem is that I cannot reproduce it myself... do you need to
follow any steps? Does the Evolution window appear, are you able to
see anything before the crash?
