GCC linker error, relocation overflow / Internal compiler error

Hi

I have a problem when linking an application compiled with GCC for c6x (v 4.5-124).

I get the following error message during linking:

pr-support.c:(.text+0x1074): relocation truncated to fit: R_C6000_PCR_S21 against symbol `abort' defined in .plt section in /home/vagrant/repositories/ti_toolchain/gcc-c6x/bin/../c6x-uclinux/libc/lib/crt1.o
/home/vagrant/repositories/ti_toolchain/gcc-c6x/bin/../lib/gcc/c6x-uclinux/4.5.1/libgcc.a(emutls.o): In function `__emutls_get_address':
emutls.c:(.text+0x68): relocation truncated to fit: R_C6000_PCR_S21 against symbol `malloc' defined in .plt section in /home/vagrant/repositories/ti_toolchain/gcc-c6x/bin/../c6x-uclinux/libc/lib/crt1.o
emutls.c:(.text+0xa4): relocation truncated to fit: R_C6000_PCR_S21 against symbol `memcpy' defined in .plt section in /home/vagrant/repositories/ti_toolchain/gcc-c6x/bin/../c6x-uclinux/libc/lib/crt1.o
emutls.c:(.text+0xec): additional relocation overflows omitted from the output
collect2: ld returned 1 exit status

The application is almost 5 MB.

We have tried to add -mlong-calls as suggested in 8.QA http://linux-c6x.org/wiki/index.php/FAQ.

This however provokes several compilation errors like this:

algdat/adstringhelper.h: In function 'void ADStringSetSignedNumber(ADString&, T, int, int, char) [with T = int]':

                    (const_int 1 [0x1])
                ] 10)
            (clobber (reg:SI 35 B3))

Any suggestions on how to resolve this?
