on linux [glibc|musl] tcc segfaults at tccdbg.c:1961 when compiling int foo; void bar(void) {} with -c -fcommon -g: tcc -c -fcommon -g test.c I have no idea why s1->sections[sh_num] is NULL in this case. s1->sections[0] is also NULL, sh_num is 10
I just pushed a fix. The code should have checked for SHN_COMMON section. This is only a problem with stab debug format. The dwarf debug format works fine.
