  • [ABANDONED] *Apparent BUG, ver: 3.22a* Variables out of scope when should not be!

    Here is a snippet of my code. currString and currDot are out of scope in the watch window and mouse over will not show a variable. NOTE: This is C++.

    STM32F4, and here is the gcc --version output

  • Hello,

    Thank you for your inquiry.
    Such an issue is not known to us.
    Could you provide a simple reproducer that could run on an STM32F4 eval board?
    The compiled elf file and the source file in question should be sufficient.

    Best regards,
    Nino
