>Description:
I have a program called "main". Program is compiled in a following way:
gcc -O0 -pipe -fno-omit-frame-pointer -std=gnu99 -c main.c
ctfconvert -L VERSION -g main.o
gcc -O0 -pipe -fno-omit-frame-pointer -std=gnu99 -o main main.o
ctfmerge -L VERSION -g -o main main.o
When I run it couple of times with:
dtrace -q -s test.1.d -c ./main
Kernel dies with
Trying sleep, but thread marked as sleeping prohibited
Backtrace is here:

in Perforce. Type "make freebsd" and hit:

Couple of times.
