Hi,
this is in maxima 5.10.0a (Windows)
(%i4) quad_qags(1/(x^2+1), x, 0, 1);
Maxima encountered a Lisp error:
Error in LET [or a callee]: Cannot create the file
C:/DOCUME~1/vadim/LOCALS~1/Temp/gazonk_1032_0.lsp.
Automatically continuing.
To reenable the Lisp debugger set *debugger-hook* to nil.
(%i5) :lisp *maxima-tempdir*;

It looks like gcl is not using the correct temp dir, it uses the
settings from Vadims system and not *maxima-tempdir*. It is probably a
gcl bug, I'm pretty sure it worked in 5.10.0.
