Because there is a size limitation to 64K in this software.
I prepared a single file with no includes that faithfully reproduced the bug:
bug0.cpp: In member function 'double AtomicDouble::CompareExchange(double,
double) volatile':
bug0.cpp:4999: internal compiler error: in create_tmp_var, at gimplify.c:368
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
This took me hours. THEN, I entered here the file.
This software told me when I pressed the "submmit" button that
my stuff was bigger than 64K, then IT DISCARDED ALL MY INPUT.
NICE.
I have worked like 3 hours more but the file size went down fro; 350k to 162K
only. It is becoming increasingly difficult to reduce the size.
In this times, *ANY* include directive will produce file sizes of more than
64K.
Why this stupid limitation?
