Summary: Missing check in WMesaMakeCurrent
Product: Mesa
Version: 6.5
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: Mesa core
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
I think there is a missing check in
mesa-6.5\src\mesa\drivers\windows\gdi\wmesa.c
following line 1316 in the function "void WMesaMakeCurrent(WMesaContext c, HDC
hdc)".
At the beginning of the function it says:
GET_CURRENT_CONTEXT(ctx);
WMesaContext pwc = wmesa_context(ctx);
if (c == pwc && pwc->hDC == hdc) // << This line fails
return;
but if pwc == 0, pwc->hDC throws an access violation.
You can verify this by doing:
void main(void)
{
wglMakeCurrent(0, 0);
}
