lovecodelc commented at 9:47 AM on September 30, 2016: none

i work on mac os, i compile source code with "./configure --enable-debug", when use gdb attach bitcoind's pid , it shows: "warning: unhandled dyld version (15) 0x00007fffe026ac8a in ?? ()"

i break at 0x00007fffe026ac8a, it actually break "main" function? and it show "?? ()" ?? but i file bitcoind symbol tables, it does not work.

do you have such problems when develop program on mac os? thank you.

This looks like a local problem on your system, or a general issue with MacOSX debugging. Do you have success debugging any other locally compiled code?

GDB itself seems to be somewhat broken on the latest version of OS X (10.11), which seems to be Apple's fault. Try googling "During startup program terminated with signal SIG113, Real-time event 113", or for issues with "GDB OS X Sierra".

If I run GDB with bitcoin-qt

done.
(gdb) run

Trying to attach to an already running bitcoin-qt process I see the same error as you.

This Apple StackExchange answer suggests that disabling SIP is required, but I haven't tested it yet.

@fanquake thank you. i think there is something wrong with third-party library(maybe gdb version is low?) when debug bitcoin program, i write and debug another test programs successful. see here: #8812

Closing this for similar reasons as #8812
