Hello,
the stack trace should look like this with line numbers, if it helps:
0x00007...671 in __strlen_avx2 at
../sysdeps/x86_64/multiarch/strlen-avx2.S:65
0x00007...2f4 in _cups_strlcpy at string.c:739
0x00005...a31 in main at rastertopwg.c:274
0x00007...e09 in __libc_start_main at ../csu/libc-start.c:308
0x00005...1a4 <_start+36>
