--- Comment #4 from Gleb Popov <arrowd@FreeBSD.org> ---
The test program seems to work fine now:

Signal 11 in dump_trace - have 7 frames
0x201a54 <dump_trace+0x44> at /usr/home/arr/try-bt
0x8208162d3 <_fini+0x8206147d7> at ???
0x2019b0 <boom+0x10> at /usr/home/arr/try-bt
0x2019c9 <two+0x9> at /usr/home/arr/try-bt
0x2019d9 <one+0x9> at /usr/home/arr/try-bt

0x82305c234 <__libc_start1+0x124> at /lib/libc.so.7

Let's close this?
