Including <execution> behaves differently depending on whether you have
the TBB headers installed or not. Without them installed, the modules
tests PASS, but with TBB headers installed they FAIL with:
gcc/testsuite/g++.dg/modules/xtreme-header-2_a.H: internal compiler error: in
core_vals, at cp/module.cc:6631
This seems likely to be due to use of the optimize pragma or attribute
in TBB headers.
Remove <execution> from those tests, so that they behave consistently
for everybody, and don't fail for people (like me) who routinely test
with TBB headers installed so that libstdc++ PSTL is thoroughly tested.
gcc/testsuite/ChangeLog:
* g++.dg/modules/xtreme-header-2.h: Do not include <execution>.
* g++.dg/modules/xtreme-header-2_a.H: Adjust dg-skip-if comment.
* g++.dg/modules/xtreme-header-2_b.C: Likewise.
* g++.dg/modules/xtreme-header.h: Do not include <execution>.
---
v2: keep the dg-skip-if directives by adjust their comments.
