an1388-serial, big file, stack smashing detected

[jaromir-sukuba]

I'm using bootloader from AN1388 via UART, recompiled for PIC32MX370F512H with pic32prog. It works just fine form smaller binaries, though when uploading bigger one, it fails after a few sectors:
./pic32prog -d an1388:/dev/ttyUSB0 uu.hex Programmer for Microchip PIC32 microcontrollers, Version 2.0.203 Copyright: (C) 2011-2015 Serge Vakulenko Adapter: AN1388 UART Bootloader Version 1.0 Program area: 1d000000-1d07ffff Processor: Bootloader Flash memory: 512 kbytes Boot memory: 80 kbytes Data: 394940 bytes Erase: done Program flash: ######*** stack smashing detected ***: ./pic32prog terminated Aborted
I'm not sure whether this is problem with particular hex file, anyway it's available here

I tried running both linux32 and linux64 versions, behaving the same. My OS is Linux Mint 18.3

EDIT:
It seems to be related to file size. I disabled a few parts of the firmware to be uploaded, binary is smaller, problem occurs much later in the process:

The smaller file is available here

@jaromir-sukuba Jaromir, can you please try to build pic32prog with -m32 option?
This bug is probably related to 64-bit architecture.
Just add -m32 to CFLAGS in makefile and run "make clean; make".
