vdrift: ir_constant_expression.cpp:134: virtual ir_constant* ir_expression::constant_expression_value(): Assertion `op->type->base_type == GLSL_TYPE_INT' failed.
SIGABRT detected, releasing the mouse
Is the shader source for this application available?
Something strange is happening here. The assertion that is hit occurs while the compiler is trying to constant-fold int-to-float operations. The type of the source should be int, but it's not.
Can you run this application in GDB and 'up' until GDB says it's in ir_expression::constant_expression_value. Then 'print op->type->name' and 'print op->type->base_type'.
The shader sources are available in the data/shaders dir in the game tarball. gdb says it tried to compile data/shaders/lightaccumulate/fragment.glsl when the assert happened.
the types according to gdb:
(gdb) f 4
#4 0xabd722cf in ir_expression::constant_expression_value (this=0x8535620)
134 assert(op->type->base_type == GLSL_TYPE_INT);
(gdb) print op->type->name
$1 = 0x83bd168 "float"
(gdb) print op->type->base_type
$2 = GLSL_TYPE_FLOAT
This bug has *NOTHING* to do with the r300 driver. The issue is completely in the GLSL compiler. Please don't change the component back. I set the component to glsl-compiler intentionally.
Sorry, I didn't do it intentionally. I had the bug opened in a tab, got your mail, did a refresh before posting the reply and the checkbox remained at r300g instead of changing into your setting. I hope it stays OK now.
It looks like this is the same problem as bug #32287. Could you check to see if the commit mentioned there fixes this problem? If that commit fixes this problem, we'll close this bug as a duplicate of #32287. That bug is remaining open until the patch is cherry-picked back to 7.10 and 7.9 release branches.
Yes, that commit fixed this problem.
