I've been experiencing segfaults in evas_cache for quite some time now.
They occur after an image that has been loaded using evas is deleted or
moved, however they are not reproducible all the time. Valgrind is also
being quite vocal in this situation. I've attached the valgrind output
and a gdb backtrace for anyone familiar with the evas internals who has
a free time to look into it.
I wonder if my e17 segfaults are related to this. I have been getting
frequent segfaults since an update of e from svn yesterday. An example bt
is given below:
#0 0x0000003f4e20d504 in __lll_lock_wait () from /lib/libpthread.so.0
#1 0x0000003f4e208ee5 in _L_lock_508 () from /lib/libpthread.so.0
#2 0x0000003f4e208d08 in pthread_mutex_lock () from /lib/libpthread.so.0
#3 0x00007fd6ff3784ac in evas_common_rgba_image_scalecache_prepare
This one sounds like referring to the scalecache, not preload.
This is just one of the bt's I have been getting. And they all crash at
different points. Maybe some common code is triggering all these
crashes? Here are some others. The first one:
