Crash on exit: assertion in paragraph_pimpl.C line 329

[Abdelrazak Younes]

Here is what I have on the console:

Assertion failed: end > start && end <= size() + 1 int __thiscall 
lyx::Paragraph::
Pimpl::eraseChars(__w64 int,__w64 int,bool) 
..\..\..\src\paragraph_pimpl.C 329
Assertion failed: end > start && end <= size() + 1 int __thiscall 
lyx::Paragraph::
Pimpl::eraseChars(__w64 int,__w64 int,bool) 
..\..\..\src\paragraph_pimpl.C 329
no buffer:
and here is a snippet of the code:

                if (i > 0 && i < fontlist.size() &&
                    fontlist[i - 1].font() == fontlist[i].font()) {
                        fontlist.erase(fontlist.begin() + i - 1);
                        it = fontlist.begin() + i - 1;
                }
