SIGXFSZ signal creates defunct process in multithreaded program!!!

Hi Pijush,

[Note:  your question is off-topic for the GCC-help forum.  Questions for 
this forum are regarding GCC in particular, not general C++ questions, not 
PThread questions, not Linux questions, not Solaris questions, not other 
library questions (except where those things are interacting with GCC in 
particular).  Having said that...]

Don't do any I/O inside a signal handler.

Don't call any OS API routines inside a signal handler.

Don't call any non-re-entrant routines inside a signal handler.

If you access any global variables inside a signal handler, makes sure 
those variables are marked "volatile".

Don't do "too much work" inside a signal handler.

There's probably a few more caveats using signal handlers.  That's just off 
the top of my head.

HTH,
