Hi, I saw several bug reports on Fedora on gvim getting signal SIGSEGV at _cairo_hash_table_lookup function. It is curious that segfault happened at beginning of function, at '{', so I looked more into it. I checked backtrace in core dump, which has about 130 000 frames. These frames are mostly calling two functions - gui_update_cursor() and gui_mch_stop_blink() - I think there is infinity loop between these two functions, so gvim ate all stack memory.

My guess is the issue was introduced with patchlevel 1294, because there was added gui_mch_stop_blink() call. -- -- You received this message from the "vim_dev" maillist. Do not top-post!
