possibly - as I said, crappy debugger.

EW25524 / IDE-2671

When a breakpoint set at "memset();" triggered, the execution might halt at "__aeabi_memset(_D, _N, _C);" in DLib_Product_string.h.

I faund this (netstorage.iar.com/.../KnownProblems.html)

With IAR I was having this issue, with eclipse+GCC my code is working. Thanks RK and Dave_couling for helping.

perhaps you just have a crappy debugger and need to step past that line and not try to step over/into it.

Dave_couling As you asked before entering memset (memset at which debugger stopping) call, address of the variable/structure is char_md address 20003660 and debugger crashed at this memset call.

Thank you all for helping me. Are you guys able to see my .map file. I attached but I can't see. If you guys are not seeing that let me know I will attach again.

cccd_md address 20003628. My code is not stopping at any specific memset() function. It is random but every time if debugger stops/crash, that always happening at any memset() function. The address I mentioned once debugger stopped there but when i was reading that address debugger didn't stop.

well it would be on the stack so it would be very surprising were it either invalid or non-aligned.

Before you enter the memset call, what is the address of cccd_md?

Okay.. sorry for that.

I updated a picture, that will tell you where debugger stopping.

I attached .map file too. Thanks for your response RK

My code is stopping at any memset() function, not any specific one during debug.

When I am stepping through, It just stops there, can't step to next statement. Sometimes, it jumps to `

__EFF_NENR1R1 __ATTRIBUTES void * memset(void * _D, int _C, size_t _N)
  {
    __aeabi_memset(_D, _N, _C);
    return _D;
  }`

this is in IAR Systems\Embedded Workbench 8.0\arm\inc\c\DLib_Product_string.h file.

don't see how you can crash on that line of code - please provide more information about what 'crash' means?
