Subject: fatal signal 6: from syntax error in header file
Organization: GNUs Not Usenet
Distribution: gnu
Date: Mon, 14 Sep 1992 17:28:57 GMT

The following bug reports the generating of fatal signal 6.  There is a
syntax error in an included header file, which seems to cause the problem.
I have included (1) the file main.cc, (2) the include file myfstream.h, (3) a
script of the -v output from the compiler in which the fatal signal is
generated and (4) the -E output of the compiler.  Each of the above sections
is prefaced by the string '******' followed by the corresponding number above.

The obvious syntax error in the header file myfstream.h is that there is
a missing semi-colon after the last declaration.  The error goes away if
the semi-colon is inserted.  This was a frustrating bug, since I had no
idea that I had a syntax problem, but instead the compiler reported a problem
with a different include file altogether, so it took me a very long time to
figure out the bug.  The compiler told me there was a problem with the
<builtin.h> header file, which was included on the line above the include
line for "myfstream.h".  So I spent considerable time trying to figure out
why the standard builtin.h file was suddenly causing problems when it hadn't
been altered for several months.....

Anyway, please let me know the results of this report, if it is investigated.
It may be the same bug that I reported several weeks ago, which caused a
fatal signal 6.  That case also was traceable directly to a syntax error
in a header file.....
