[Mono-list] PIOCSTATUS failed in restart_all_lwps

[yruss972]

Hi,

I'm running Mono 2.6.1 on Solaris 10 Sparc. 
The signcode utility is dumping core, seemingly at random with the following
error:

PIOCSTATUS failed in restart_all_lwps
Stacktrace:

Abort - core dumped


Here is the stack trace from the core dump:
