MFS Crash with Heavy Weight Memory Allocator

I have an issue where MFS appears to be crashing during init.  The only change I made to the "out-of-box configuration" is to not use the Light Weight memory allocator.  There seems to be enough spare memory available, so I don't think that is the issue.  Configuration:


MQX           4.0.0

BSP:          TWRK60F120M

Project:       rtcs_shell

Config:        debug

Tools:         Keil UV4




Added the following line to user_config.h


#define MQX_USE_LWMEM_ALLOCATOR             0


The initialization crashes here:


Call stack looks like this:


     mqx_status = _io_mfs_install(dev_handle1, "a:", (_file_size)0);





Crash is right after the _int_enable()


             /* allow pending interrupts */





Any ideas?
