I am compiling code to run on an embedded platform using a 80188 processor and 256K of RAM space.  I am building using C++ version 4.52.  Looking at the .LOC file whenever the FARHEAP gets above 0x1F000 the system just resets.  I have tracked it down to the Initialize routine in BCPP45.ASM.  The code never returns from this function call.

Initialize jumps through a table of pointers to initialize RAM variables,  The number of intializers is calculated and a loop is performed calling these intializers. Either the routine never thinks its done, and my watchdog system causes a reset, or one of the entries is causing a systm reset.  I believe the later is happening.

I no longer have manuals for this compiler and the platform is an old product thats needs revision.  I can supply the Makefile, BCPP45.ASM .RM and .LOC files if needed.

Thanks in advance for any help I can get here I'm totaly frustrated.

Mike
