[Bug libc/3462] New: Malloc memory corruption when malloc(...) called

[Bug libc/3462] New: Malloc memory corruption when malloc(...) called

[jrweave at gmail dot com]

I simple call to malloc results in the following error:

*** glibc detected *** malloc(): memory corruption: 0x00000000005b61c0 ***

I am requesting 5750*380*8 (17,480,000) bytes of data.  I am running on an 
Intel Woodcrest system (em64t architecture).  Many calls to malloc ask for 
similar sizes of memory before this call, but none of them fail.  This call 
consistently fails every time.

Due to the complexity and proprietary nature of the code, I cannot send a 
sample.  However, it occurs exactly as described above.

The message clearly says that glibc *detected* the problem.  Not caused it. 
Your program is corrupting memory somewhere somehow and glibc finally notices
it.  Use valgrind or mudflap or similar tools to detect your mistake.
