Dear Maintainer,
GDB 10.1 is unable to debug binaries produced by GCC 11.2.0 with the
-gsplit-dwarf switch. GCC 11, which is now in Debian sid, uses DWARFv5
debugging format by default. With -gdwarf-4 the error does not appear.
builder@barberry:/tmp/tmp.qHMJOXsPej$ cat hello.c
#include <stdio.h>
int main()
{
puts("Hello everybody!");
return 0;
}
builder@barberry:/tmp/tmp.qHMJOXsPej$ gcc -g -gsplit-dwarf -c hello.c
builder@barberry:/tmp/tmp.qHMJOXsPej$ gcc hello.o -o hello
builder@barberry:/tmp/tmp.qHMJOXsPej$ gdb -silent hello
Reading symbols from hello...
Dwarf Error: wrong unit_type in compilation unit header (is DW_UT_split_compile
(0x05), should be DW_UT_type (0x02)) [in module /tmp/tmp.qHMJOXsPej/hello.dwo]
(No debugging symbols found in hello)
(gdb) q
The attached patch against GDB in unstable seems to be fixing the issue.
