Summary: glBindTexture causes a segmentation fault with invalid
targets
Product: Mesa
Version: CVS
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
This is arguably a bug in the program using mesa, but it'll be nice if mesa
doesn't crash :)
calling glBindTexture with an invalid target (0 in my case) causes a segfault.
top frames from the backtrace are:
Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread -1230031168 (LWP 5066)]
valid_texture_object (tex=0x0) at main/texobj.c:233
233 main/texobj.c: No such file or directory.
in main/texobj.c
Current language: auto; currently c
(gdb) bt
#0 valid_texture_object (tex=0x0) at main/texobj.c:233
#1 0xb67b4de8 in _mesa_BindTexture (target=0, texName=0) at main/texobj.c:910
In this particular case, the texName is 0. The code has a comment:
840 /* newTexObj = a default texture object */
841 switch (target) {
[...]
863 default:
864 ; /* Bad targets are caught above */
865 }
but i don't see any code that catches the bad targets. The result is that
newTexObj is NULL and the assert on valid_texture_object(newTexObj) causes a
segfault.
