The gcc.dg/cpp/trad/include.c -fno-show-column compilation test ICEs with...

<built-in>:0: internal compiler error: Abort trap
Please submit a full bug report,

No luck so far in getting a backtrace. Same error at -m64.

------- Comment #1 from pinskia at gcc dot gnu dot org  2008-12-01 00:17 -------
I had the same thing for the PS3 compiler, it turned out due to C++ style
comments in the system headers.  This was causing libcpp to abort.

------- Comment #2 from howarth at nitro dot med dot uc dot edu  2008-12-01 14:23 -------
I don't see any c++ comments in the included system headers. Is there a way in
gcc to dump the preprocessed source in a manner that won't parse out the
comments? When I dropped the '-fno-show-column  -traditional-cpp' flags, the
abort was eliminated but the resulting include.i is missing the comments. A
manual search of the system headers didn't show any but it would be nice to be
able to verify through gcc.

------- Comment #3 from tromey at gcc dot gnu dot org  2009-01-02 16:44 -------
You can try -C to keep the comments.

In the original report you said you can't get a backtrace.
That makes it a lot harder :(

Could you try shrinking the test case somehow?
Or perhaps you could change the abort() calls in libcpp to something
that would print __FILE__ and __LINE__.  That might help a little.

------- Comment #4 from pinskia at gcc dot gnu dot org  2009-01-02 17:09 -------
Here is a reduced testcase:
t.c:

#include <t.h>


--- CUT ---
t.h:

#ifdef __PME__

#define _TLS_QUAL /*0123456790*/

#endif // __PME__

Compile with "gcc t.c -isystem . -traditional-cpp".

I can reproduce the abort on both i686-linux-gnu and i386-darwin8.11 with my
reduced testcase.

------- Comment #6 from howarth at nitro dot med dot uc dot edu  2009-01-02 22:40 -------
The test case from Comment 4 triggers the error on x86_64-apple-darwin10 as
well.

------- Comment #7 from howarth at nitro dot med dot uc dot edu  2009-02-21 20:18 -------
This problem in darwin10 is in fact due to c++ comments in
/usr/include/Availability.h  and /usr/include/AvailabilityInternal.h. Replacing
those with c style comments allows the gcc.dg/cpp/trad/include.c
-fno-show-column testcase to pass without ICE'ing.

------- Comment #8 from howarth at nitro dot med dot uc dot edu  2010-03-10 03:47 -------
This bug is fixed for the release Mac OS X 10.6 (ie the c++ comments are
removed from /usr/include/Availability.h  and
/usr/include/AvailabilityInternal.h.
