Workaround for stack limit in windows with gnu g++

Question

Hi, I have built and compiled a command line program with GNU g++ which "overflows" the stack for a number of reasons, mainly deep inheritance, lots of objects created, etc. So I followed this workaround on Mac OS X to solve the problem when linking:

-Wl,-stack_size,0x10000000,-stack_addr,0xc0000000

Under Linux, I just tried ulimit -s unlimited; running the program in this way does not give a segmentation fault any more

But when trying to compile it on Windows with GNU g++, the compiler does not recognize

-Wl,-stack_size,0x10000000,-stack_addr,0xc0000000

What other option would you use as a workaround for the problem?

Thanks in advance

Answer 1

-Wl,--stack,somelargesize looks like what you're after. However, I'd strongly recommend refactoring your code to make use of the heap for large allocations instead. Address space is a finite resource and your "workaround" asks for quite a large chunk of it.

Answer 2

This page suggests that you might want to try the following command line option (search for -fno-stack-limit):

-fno-stack-limit

If that fails on its own, then this other page suggests to also add:

-fstack-check

Answer 3

it works now, thanks!
