Re: LyX 2.5.0 RC2 crash report Mac M2 Tahoe 26.1

2025/12/20 1:44、Jean-Marc Lasgouttes <lasgout...@lyx.org>のメール: It would be interesting to see what theBufferList().isLoaded(buf) and theBufferList().isInternal(buf) return in the helper destructor. The question is to know how it is possible to detect that the buffer has been destroyed. After evaluation of the “for” sentence in ~UndoGroupHelper() (line 716), we have: d->buffers_ has 1 item buf has an address theBufferList() has an address -> binternal 0items -> bstore 0items theBufferList().isLoaded(buf) <no such value> theBufferList().isInternal(buf) <no such value> Do you see some backtrace leading to the destructors. I attach them to this mail. JMarc Koji
