possible Deadlock when MALLOC_CHECK is set to 2 - help needed

[C Mohankumar-A17025]

Hi,

 

I am facing a deadlock problem when MALLOC_CHECK is set to 2.

My application had some memory allocation issues and to trace the problem, I have set the MALLOC_CHECK to 2 so that the progrma crashes when the problem is encountered. Now, I also have a signal handler installed which needs some memory allocation.  My application raises the interrupt within mallow_check()  or free_check() and the signal handler is getting invoked. Within the handler, invocation of malloc() results in the process going into a deadlock.

 

  Can someone tell me is it safe enough to call these malloc() recursively?

 

Thanks,

Mohan
