Description

Proposed patch sent upstream. This is what I could reproduce (this is a racy bug, doesn't always happen): When the display channel is destroyed, we disconnect all signals handlers, but we don't remove the reference on the primary surface data, and that can lead to crashes in a later expose event, reusing the canvas surface (ex, if scaling is disabled). Call primary_destroy() when disconnecting the channel from the widget. We now keep the primary surface during channel reset (right after disconnect for example), so the primary surface can be eventually recycled, and the widget still holds a valid reference until the signal is received. The primary surface is ultimately destroyed during finalize, or if the new primary surface size doesn't match. Program received signal SIGSEGV, Segmentation fault. __memmove_ssse3_back () at ../sysdeps/x86_64/multiarch/memcpy-ssse3-back.S:2130 2130 lddqu -68(%rsi), %xmm0 Missing separate debuginfos, use: debuginfo-install gtk2-engines-2.20.2-2.fc15.x86_64 libusb1-1.0.9-0.3.rc1.fc16.x86_64 p11-kit-0.6-1.fc16.x86_64 (gdb) bt at ../sysdeps/x86_64/multiarch/memcpy-ssse3-back.S:2130 srclen=<optimized out>, srcinc=4096, destinc=68, height=<optimized out>, half_order=0) at /usr/include/bits/string3.h:52 dest_bits_per_pixel=32, req_yoffset=<optimized out>, req_xoffset=0, image=0x7fffffffb9a0, req=<optimized out>, dpy=0x64a630) at PutImage.c:821 req_height=<optimized out>, req_width=<optimized out>, y=<optimized out>, x=0, req_yoffset=<optimized out>, req_xoffset=0, image=0x7fffffffb9a0, gc=0xa817e0, d=33554452, dpy=0x64a630) at PutImage.c:870 req_xoffset=0, req_yoffset=<optimized out>, x=0, y=26, req_width=17, req_height=20, dest_bits_per_pixel=32, dest_scanline_pad=32) at PutImage.c:908 image=0x7fffffffb9a0, req_xoffset=0, req_yoffset=0, x=0, y=26, req_width=17, req_height=20) at PutImage.c:1027 image=<optimized out>, src_x=0, src_y=0, width=17, height=20, dst_x=0, dst_y=26) at cairo-xlib-surface.c:1357 ---Type <return> to continue, or q <return> to quit---c height=20, width=17, dst_y=26, dst_x=0, src_y=<optimized out>, src_x=<optimized out>, pattern=0x7fffffffc6b0, op=CAIRO_OPERATOR_OVER, surface=0xb9a650) at cairo-xlib-surface.c:2403 dst_y=26, dst_x=0, mask_y=0, mask_x=0, src_y=26, src_x=0,
