The source in the Testsuite Directory contains an error (misnamed file) which
when corrected will allow gcc to compile correctly. It is the "File Not Found"
error that causes the ICE and NOT an "error in the Testsuite source" itself.
If you alter the Source to correct it then the ICE goes away.
This message suggests that this Bug still occurs on the Trunk and purports a
Fix: http://readlist.com/lists/gcc.gnu.org/gcc/8/41545.html
I get this Bug on a preRelease SVN version:
# /usr/local/gcc-4_5-branch_build/gcc/xgcc -v

extern int zz;
If I edit a copy of common-1.c and include "common-1.hs" (instead of
"common-1.h") then the ICE does not occur (so no preprocessed source included).
Here is a small portion of gcc.log:

-----
Perhaps more troubling is that if I run this by hand from the command line
(instead of letting the Testsuite run it) then I get a "normal error" and no
ICE.
So we have:
* Testsuite's gcc.log shows different output than using the command line.
* In the common-1.c File the "#include" references a file we do not have _OR_
we create the File to be included with a name differing from what the Source
expects.

/usr/local/gcc-4_5-branch/gcc/testsuite/gcc.dg/pch/common-1.c:1:22: fatal
error: common-1.h: No such file or directory
compilation terminated.
