Hello, all

I've faced a problem about :forrtl: severe (174): SIGSEGV, segmentation fault occurred when I try to run FVCOM code on Linux (colorado) system.

I want to use -heap-arrays as recommended, however, I'm not sure if I used the right format of it.

-bash-3.2$ ifort -heap-arrays 10 fvcom

Any suggestion to solve this problem?
Thanks.

Are you hoping to use ifort to reconfigure an executable without a full rebuild?  That doesn't work.  You must rebuild each procedure you want to switch e.g. ifort -c -heap-arrays *.f and re-link from object files and libraries.

You probably want heap-arrays with no size specifier, which will make all alllocations on heap.  The size specifier keeps all allocations of size which is not known at compile time on stack.

Adding the -traceback option to the link step may help in finding where a segv occurs by running under debugger.   Such hints should be included in the paper on resolving segv which should be referred to in "useful information..." at the top of the forum.

By the way, you posted in the Windows forum; there is a separate one for linux.
