I was using the wrong flags, with -m32 -D_GLIBCXX_DEBUG it fails on gcc-12:
Schedule of variations:
unix/-m32/-D_GLIBCXX_USE_CXX11_ABI=0
Running target unix/-m32/-D_GLIBCXX_USE_CXX11_ABI=0
Using /usr/share/dejagnu/baseboards/unix.exp as board description file for
target.
Using /usr/share/dejagnu/config/unix.exp as generic interface file for target.
Using /home/jwakely/src/gcc/gcc-12/libstdc++-v3/testsuite/config/default.exp as
tool-and-target-specific interface file.
Running

...
FAIL: 22_locale/money_get/cons/3.cc (test for excess errors)
FAIL: 22_locale/money_put/cons/3.cc (test for excess errors)
And also still fails on trunk after r13-6905:

Comment 1 is fixed on trunk now though, thanks.
