These messages are internal to valgrind, but they have some utility for users. They indicate that valgrind's memory manager was asked to handle a block (actually a single contiguous address interval, which could be a block or a non-block) of more than 100,000,000 bytes. Such a large interval is unusual and might indicate an error, especially on a system with 32-bit addresses. But on x86_64 with 64-bit addresses and much more latitude for placemement of PT_LOAD, this might be OK. Where are your PT_LOAD? [readelf --segments <executable>] When I was working in this area of valgrind, then I improved the message to include the actual address values as well as the length. Often this made it easy to determine whether to be concerned. -- ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ Valgrind-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/valgrind-users
