Re: Help on G77 under opteron AMD 64bit

we are currently tracing a problem on some old Fortran code using G77 on an AMD 64 bit Opteron machine. We understood that local variables are put in the stack area (i.e. with addresses > 2**32), which causes our deprecated and ugly code to fail.

Try -fno-automatic -finit-local-zero and report back how far you got.


Thanks in advance,
