This warning is probably a false alarm, but it's trivial to fix.
| ../glx/createcontext.c: In function ‘__glXDisp_CreateContextAttribsARB’:
| ../glx/createcontext.c:172:24: warning: dereference of NULL ‘0’ [CWE-476] [-Wanalyzer-null-dereference]
| 172 | switch (attribs[i * 2]) {
| | ~~~~~~~^~~~~~~
The situation is too complex for the analyzer to handle:
(but also not immediately clear for the human reader)
* `attribs` is only NULL when req->numAttribs is 0
* in that case, the for loop is no-op, so `attribs` won't ever be deref'ed.
We can make it easier for both analyzer as well as human reader by just putting
the whole loop into an `if (req->numAttribs)` and assigning it inside there.
There shouldn't be any (practically measurable) extra cost.
