runtime: openbsd crash (possible dup: 3102) #3166
Labels
Comments
My guess is that this is a duplicate of issue #3102. Labels changed: added priority-later, removed priority-triage. Owner changed to builder@golang.org. Status changed to HelpWanted. |
Yes, this is a duplicate of 3102. This occurs when a new thread is receiving and processing a signal (usually on the return from the rfork syscall) and has not yet switched to its own stack. This is addressed by the following change: http://golang.org/cl/5757064 |

What steps will reproduce the problem? 1. use amd64 OpenBSD-current 1. checkout current tip 2. run the src/all.bash script with bash What is the expected output? go builds. What do you see instead? Most of the time, the compiler hangs while building the "math" or the "regex" package. But sometimes I get an error instead: # Building packages and commands for openbsd/amd64. runtime errors sync/atomic unicode math runtime: split stack overflow: 0x20c8bfe78 < 0x20c8c0000 throw:
