Apart from the fact that I don't have the time to click for half an hour:
valgrind --tool=memcheck --workaround-gcc296-bugs=yes --leak-check=yes
-v ./lyx 2>e.log
results in a segmentation fault and the attached file e.log. Running LyX
directly works. Removing the memcheck options does not alter the result.
Do we have any valgrind expert here who can make sense of this or tell me
how I can find out where the segmentation fault happens?
