Just tried building gcc-4.6.3 as DJGPP cross-compiler running on Ubuntu, but
encountered a very similar bug to this one, only occurring in cc1 instead of
cc1plus.
The compiler builds fine, but then, when it has to compile libgcc, it
segfaults.
I tried running the compiler with a trivial C program (int main(){return 0;}).
It segfaults.
I tried to debug cc1 with gdb. The lines causing the crash are in c-common.c:
int16_type_node =
TREE_TYPE (identifier_global_value (c_get_ident (INT16_TYPE)));
The call to identifier_global_value() returns NULL, and the pointer is
dereferenced by the macro TREE_TYPE, causing the crash.
This means that DJGPP cannot be used as a target with recent versions of gcc.
It may be little used nowadays, but, since it is not unsupported, it should
work.
