[Bug c++/38485] New: possible regression: expected primary-expression at end of input
Compressed .ii file goes as attachment.
gcc 4.3.2: (reports no errors)
my gcc:
g++ -c kded_kephal_automoc.ii
In file included from
/src/a/kde/4.1.80/o/kdebase-workplace/libs/kephal/kded_kephal/moc_xmlconfigurations.cpp:11,
from
/src/a/kde/4.1.80/o/kdebase-workplace/libs/kephal/kded_kephal/kded_kephal_automoc.cpp:6:

error: expected primary-expression at end of input
g++ -v
Using built-in specs.
Target: x86_64-unknown-linux-gnu
Configured with: ../svn/configure --prefix=/usr --enable-threads
--enable-shared --enable-languages=c,c++ --host=x86_64-unknown-linux-gnu
--with-system-zlib --with-x --enable-java-awt=gtk

--enable-__cxa_atexit --enable-libada --enable-gtk-cairo
--enable-libgcj-multifile --with-long-double-128 --disable-nls
Thread model: posix
gcc version 4.4.0 20081211 (experimental) (GCC)
The problem is at line 9355 of the .ii: (comment it out and it works)
void translateToOther(QMapint, QRect layout, Output * base, QMap
int, int match = (QMapint, int()));
...and from what I could figure out, it is the right-side of the '=' default
parameter assignment.
From my understanding, the code sould be equivalent to this small test case:
template typename T1, typename T2 class blah {
T1 whatever1;
T2 whatever2;
public:
inline blah() {}
inline T1 get1() { return whatever1; }
};
int foo(blah int, int bar = (blah int, int ())) {
return bar.get1();
}
int main(void) {
return foo();
}
However, this code compiles and runs perfectly on my gcc.

--- Comment #5 from gcc at spatium dot org 2008-09-28 17:27 --- Subject: Re: [4.4 Regression] gcc-4.4-20080919 ada build failure What happens if you don't use profiledbootstrap but instead bootstrap? I did make bootstrap in the very same directory and it built everything okay. However, note that I'd like very much to be able to profiledboot, especially since another profiledbootstrap bug was fixed only recently. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37601
