I interrupted with GDB and made a trace: #0 0x00007f650ee794e7 in __memcpy_ssse3 () from /lib64/libc.so.6 #1 0x00007f650776a390 in blob_write_bytes () from /usr/lib64/dri/radeonsi_dri.so #2 0x00007f650776a4e8 in blob_write_uint32 () from /usr/lib64/dri/radeonsi_dri.so #3 0x00007f6507636421 in serialize_glsl_program () from /usr/lib64/dri/radeonsi_dri.so #4 0x00007f6507638132 in shader_cache_write_program_metadata(gl_context*, gl_shader_program*) () from /usr/lib64/dri/radeonsi_dri.so #5 0x00007f65074a9a38 in link_program_error () from /usr/lib64/dri/radeonsi_dri.so #6 0x00007f6509d85a3d in deoglShaderLanguage::pLinkShader (this=0x7f65004360c0, handle=298) at src/modules/graphic/opengl/src/shaders/deoglShaderLanguage.cpp:1272 #7 0x00007f6509d86537 in deoglShaderLanguage::CompileShader (this=0x7f65004360c0, program=...) at src/modules/graphic/opengl/src/shaders/deoglShaderLanguage.cpp:530 Mesa gets stuck inside "link_program_error" => "shader_cache_write_program_metadata" => "serialize_glsl_program" . Most probably serialize_glsl_program goes rampage there but I have no idea if this is the real reason. According to the massif logs though ralloc_size is called with GB of data multiple time in there somewhere.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
