Hello,

Could not compile ff.c (FatFs file system by ChaN). Tried to compile ff.c R0.13a and R0.13b with SDCC #9223 and #10213. The result is the same:

$ sdcc -mstm8 -c ff.c

ff.c:5960: error 9: FATAL Compiler Internal Error in file 'gen.c' line
number '3367' : Unbalanced stack.
Contact Author with source code

Compilation environment - Ubuntu 16.04 (32-bit) in the VirtualBox (5.2.8 r121009).

Is there a way to fix this issue?

Best regards,
Vladimir

    I just tried to reproduce the issue using SDCC 3.7.1 #10496. I downloaded FatFs R0.13b, and did a "sdcc -mstm8 -c ff.c" in "source/". I did not get the error.

    P.S.: I recommend to check if you still get the error using a current version of SDCC, such as the current 3.7.1 #10499.

    I am sorry, there was typo in my previous message:
    I tried to compile ff.c R0.13a and R0.13b with SDCC #10213 and #10499 (built from source code) with the same error result.

    Next I downloaded and untared last sdcc-snapshot-i386-unknown-linux2.5-20180804-10499.tar.bz2. The result is the same.

    sdcc-snapshot-amd64-unknown-linux2.5-20180804-10499.tar.bz2 + ubuntu18.04x64 gives the the same result.

    After some research I found that the problem appears when FF_USE_MKFS in the ffconf.h file is enabled:

    #define FF_USE_MKFS     1
/* This option switches f_mkfs() function. (0:Disable or 1:Enable) */

    Thanks. With FF_USE_MKFS defined I can reproduce the issue, and filed bug [bugs:#2793].
