Hi Jakub,
The difference between these two cases (one maintaining the pragma in right
place,
the other note) suggested a viable work around in the code.
I can eliminate the extra naked_for macro and (with so

Hi Jakob,
thanks for looking at this.
I'm trying to cut down a fail in 100k line of code package to the minimal thing
that I can submit.

Is the original package;

GCC preprocessor moves location of _Pragma operator in sequence in a variadic
macro:
Simpler case:
#define thread_for( i, num, ... ) for ( uint64_t i=0;i"
# 1 ""
# 1 "tmp.cc"
#pragma omp critical
# 3 "tmp.cc

Just a comment -- suggest a warning thrown if union access from
two views is made. AFAIK g++ is the only compiler not implementing the
defacto type pun use.

Signature of fail in 8.0.0 (head) is:

Just an update:
Still fails in G++ 7.1.0 and in 8.0.0 (head) on Wandbox.
Still passes in Clang 4.0.0 and 5.0.0(head).

Can confirm (5.4) that -O2 also fails,
-O1 passes.

Thanks for the quick response. Hope this more complete info is helpful.
Should give (1,0) but does give (0,0) under G++ 5.0-6.2 under -O3.

p.s. in case anyone is wondering this recursive construct is
a simplification of a construct I'm using in an expression
template framework, so this is not simply a convoluted test case.
Rather, I distilled th
