[Tinycc-devel] Bug using -g with line directive

[Levo D]

I'm interested in using tcc as a backend for debug builds in my compiler. It 
appears that when I compile with '-g' it works fine but tcc has problems when I 
use the line directive to specify my source file. Below is an example of my 
source and an example c output. If you compile the c code with 'tcc -g test.c' 
and run the gdb command below gdb will complain and show an internal error. 
This happens on linux (x86-64). On mac lldb is also unhappy

Is the below enough information as a bug report? You can use the following 
regex to remove the '#line' from the c file \t?#line.*\n

gdb ./a.out -batch -ex 'br a.bolin:5' -ex 'r'

test0() s32 {
        array := $s32[10]
        array[0] = 0
        array[1] = 3
        array[2] = 6
        array[3] = 9
        array[4] = 12
        array[5] = 15
        array[6] = 18
        array[7] = 21
        array[8] = 24
        array[9] = 27
        return array[4]
}
main() {
        test0();
}
