Just updated my 8.0-STABLE desktop to r202128 the other day and
can no longer run certain windows executables through wine without

issue lately?
I'm able to get the program to continue as normal by attaching the
pid trough gdb, but would for obvious reasons prefer not to do
that. Any help trying to find the underlying cause would be
appreciated as this has not been a problem with revisions previous
to r202128.
You can check whether the process is multithreaded (most likely, it
is), and, if so, what is the state of different threads. procstat
-t <pid> and then procstat -k <pid> would probably give some
information for the start.
Here's the output from procstat -k and -t. I've compiled my kernel
with KDB and DDB support if there is anything needed from that.

Besides weird formatting of procstat -k output, I do not see anything
wrong in the state of the process. It got SIGSTOP, I am sure.
Attaching gdb helps because debugger gets signal reports instead of
target process getting the signal actions on signal delivery.
The only question is why the process gets SIGSTOP at all.
Wine uses ptrace(2) sometimes. The SIGSTOP could have come from that.
I recently submitted http://www.freebsd.org/cgi/query-pr.cgi?pr=142757
describing a problem with ptrace and signals, so you might want to give
the kernel patch a try.
This patch fixes the issue of wine going into SIGSTOP. Thanks Tijl.
