Compile error on tru64 5.1b

Hello,

Compiling openldap 2.4.26 on tru64 unix v5.1b, using the native compilers and gmake. I'm getting an error as follows:

Entering subdirectory liblunicode gmake[2]: Entering directory `/usr/local/openldap/openldap-2.4.16/libraries/liblunicode' cc -O4 -g3 -w -I../../include -I../../include -pthread -I/usr/local/include -pthread -I/usr/local/include -c -o ure.o ure.c cc: Fatal: A memory access violation (bus error or segmentation fault) has occurred. Please submit a problem report. gmake[2]: *** [ure.o] Error 1

I retried, just in case, and got the same error again. I'm not a C programmer and I have no idea how to fix this. What can I try and send to get this fixed?

Thanks,
