Removing the "signed" qualifier, as proposed above, fixed it; I had no other problems building the cross-compiler. Attached is a patch against 5.2.0. Please note that I left "signed char" intact; this is because of -funsigned-char (and it still fixes the crash). I'd suggest to apply it and close this bug; there probably isn't anything else to do here.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41557 --- Comment #3 from Andris Pavenis 2013-01-16 18:57:42 UTC --- I also verified that I have already mostly applied a patch sent to gcc-bugs recently (http://gcc.gnu.org/ml/gcc-bugs/2013-01/msg01142.html) already for my builds, except of course one typo in the patch: +#define INT_FAST16_TYPE "int" I do not remeber any more why it was done. It would also have been be faster to report problem also to DJGPP mailing list.

It looks that in the first case (message from 2009-10-03) my build for DJGPP v2.03 has been used. For that case I would suggest to remove command line option -fpch-preprocess. I initially had problem using PCH for DJGPP and after that I always used --disable-pch. About second message: Are You using unmodified gcc sources on Ubuntu? All builds of GCC for DJGPP has additional changes to the original sources (I know it would be nice to have changes submitted). For ubunto one could try to use alien to convert my RPM packages available from ftp://ftp.delorie.com/pub/djgpp/rpms (or my latest test build at http://ap1.pp.fi/djgpp/gcc/test/4.8.0-20130111/) to .deb (I'm specially performing RPM builds to reduce possible dependence on system as much as possible so it is rather likely that packages should work on Ubuntu after converted to .deb)
Re: [Bug target/41557] gcc.exe: Internal error: (null) (program cc1plus)
After spending hours to find the cause of the segmentation fault i found out that the problem coausing source is the gcc/config/i386/djgpp-stdint.h wich uses the identifier "signed" to declare signed types. Reading the top of the c_common_nodes_and_builins() function in c-common.c it tells: /* `signed' is the same as `int'. FIXME: the declarations of "signed", "unsigned long", "long long unsigned" and "unsigned short" were in C++ but not C. Are the conditionals here needed? */ So there is no need to declare "signed [char|int|long]" when char, int and long are already signed types. The identifier_global_value() function returns 0 if the type name is not registered causing a segmentation fault in TREE_TYPE() when calling it with nil. Solution: remove all keywords "signed" in djgpp-stdint.h I've provided a patch for gcc-4.7.2 wich will probalby apply on other versions too.

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.
