mesa: 7f80041efae5be95ef53b8164e67027d234f9574 (master) Run glean api2 on 64-bit build. A SIGSEGV occurs. The SIGSEGV does not happen with a 32-bit build. The regression was introduced by the glsl branch merge. git bisect good 15a3b42e135a3a2cb463ec3cff80a55dd8528051 git bisect bad 6c03c576cc49bbb008de66d374f4302ff0fe0390 (gdb) bt full #0 0x00007fa5d27c599c in ir_has_call (ir=0x7f0000000000) at src/glsl/ir_basic_block.cpp:56 v = {<ir_hierarchical_visitor> = {_vptr.ir_hierarchical_visitor = 0x7fa5d3218230, base_ir = 0x0, callback = 0, data = 0x0}, has_call = false} #1 0x00007fa5d27a35a8 in do_dead_code (instructions=0x2d65890) at src/glsl/ir_dead_code.cpp:80 entry = 0x3234c60 iter = {<iterator> = {<No data fields>}, node = 0x3234c60, _next = 0x3234cf0} v = {<ir_hierarchical_visitor> = {_vptr.ir_hierarchical_visitor = 0x7fa5d3217770, base_ir = 0x0, callback = 0, data = 0x0}, variable_list = {head = 0x338f840, tail = 0x0, tail_pred = 0x30d8e70}, mem_ctx = 0x30171a0} progress = true #2 0x00007fa5d2792d98 in do_common_optimization (ir=0x2d65890, linked=true) at src/glsl/glsl_parser_extras.cpp:725 progress = 1 '\001' #3 0x00007fa5d27b6bc4 in link_shaders (ctx=0x2c8c5c0, prog=0x2e261e0) at src/glsl/linker.cpp:1332 i = 0 vert_shader_list = 0x3206940 num_frag_shaders = 1 min_version = 110 max_version = 110 num_vert_shaders = 0 frag_shader_list = 0x3206948 #4 0x00007fa5d26a277a in _mesa_glsl_link_shader (ctx=0x2c8c5c0, prog=0x2e261e0) at src/mesa/program/ir_to_mesa.cpp:2741 i = 1 #5 0x00007fa5d266845e in link_program (ctx=0x2c8c5c0, program=5) at src/mesa/main/shaderapi.c:829 shProg = 0x2e261e0 obj = 0x2cd1720 __FUNCTION__ = "link_program" #6 0x00007fa5d266916b in _mesa_LinkProgramARB (programObj=5) at src/mesa/main/shaderapi.c:1342 ctx = 0x2c8c5c0 #7 0x0000000000489a84 in GLEAN::API2Test::createProgram(unsigned int, unsigned int) () No symbol table info available. #8 0x0000000000489f3a in GLEAN::API2Test::testUniformfFuncs() () No symbol table info available. #9 0x000000000048afad in GLEAN::API2Test::runSubTests(GLEAN::MultiTestResult&) () No symbol table info available. #10 0x000000000048b03e in GLEAN::API2Test::runOne(GLEAN::MultiTestResult&, GLEAN::Window&) () No symbol table info available. #11 0x000000000048bda7 in GLEAN::BaseTest<GLEAN::MultiTestResult>::run(GLEAN::Environment&) () No symbol table info available. #12 0x000000000048354f in main () No symbol table info available.
