The issue (or maybe a similar issue) is apparently very old: 
http://bugs.freepascal.org/view.php?id=17921 (printer, but crashed 
immediate)
but  appears to be an issue in GDB, that can not be fixed in Lazarus itself

Their has been another similar issue: 
http://bugs.freepascal.org/view.php?id=19883  (crash after app terminates)

The latter can be solved by upgrading GDB:
Either get the latest mingw, or you can find them here:
http://svn.freepascal.org/svn/lazarus/binaries/i386-win32/gdb/bin/

The svn link can be accessed in the browser. MinGW was recently updated, 
and is newer. But has not yet been tested.

However all GDB 7.3 appear to suffer from an old problem that *seems* to 
have been fixed in gdb versions from 7.0.50 to 7.2 => but it requires a 
very unlikely race condition, and even then does not always trigger.
