Bug ID: 60736
Summary: Crash in preprocessor including stdc-predef.h when it
does not exist on glibc-based systems
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Keywords: ice-on-invalid-code
Severity: normal
Priority: P3
Component: preprocessor
Assignee: unassigned at gcc dot gnu.org
Reporter: ian at airs dot com
The file stdc-predef.h is special on glibc-based systems, as GCC pretends that
it does a #include of that file first. My system (Ubuntu Precise) does not
have stdc-predef.h. That case is supposed to work. However, if the program
attempts to #include <stdc-predef.h>, which should fail, the compiler crashes
rather than reporting an error.
In other words, on a system without <stdc-predef.h>, this crashes:
echo "#include <stdc-predef.h>" | gcc -x c -
<stdin>:1:0: internal compiler error: Segmentation fault
