https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=183040 --- Comment #4 from commit-hook@freebsd.org --- A commit references this bug: Author: nwhitehorn Date: Wed Jun 4 06:21:55 UTC 2014 New revision: 267040 URL: http://svnweb.freebsd.org/changeset/base/267040 Log: MFC r266778: Repair nested signal handling on PowerPC. The signal trampoline code was not allocating space for the parameter save area in the stack frame. If the compiler chose to save the argument to the signal handler on the stack, it would overwrite the first 32 bits of the sigaction struct with it, corrupting it for a subsequent invocation.
