[Bug libc/2482] New: When sending signal to my applications, some of the core routines such as malloc,free, fclose,fopen hangs

["manus at eiffel dot com" <sourceware-bugzilla at sourceware dot org>]

Hi,

I have a multithreaded application and I send a SIGUSR2 signal to let it know 
it should terminate. In the code I have which terminates it after the signal 
handler terminated by a call to longjmp, I do calls to malloc, free, fclose, 
fopen. Very often my application deadlock in those routines.

Is this a bug, or am I not doing something right with the handling of signals?

I'm using RedHat 7.1 on a dual processor. The version of glibc I have is 2.1.92.

Thanks,
Manu
