Overview

Bug fix release mostly to correct the bugs in 5.5.0 which broke the DMALLOC_FUNC_CHECK compile flag. Also improved some testing and discovered and fixed some user-pointer checking bugs.

New Functionality

• Improved the testing of user pointers used in DMALLOC_FUNC_CHECK function pointers.
• DMALLOC_FUNC_CHECK was not checking atoi, atol, and memmove because of an oversight. It does now.

Dmalloc Utility Changes

None.

Changes in the Debug Tokens

None.

Changes to the settings.dist File

None.

Installation Changes

None.

Programming Notes

• Added the dmalloc_verify_pnt_strsize() routine which allows you to verify a pointer with both a strlen flag and a max-size argument.
• Improved the way the library tests user pointers in the DMALLOC_FUNC_CHECK routines.
• Added missing DMALLOC_FUNC_CHECK routines: atoi, atol, and memmove.

Environmental Variable Changes

None.

Bugs Fixed

• Fixed a problem which broke the usage of the DMALLOC_FUNC_CHECK compilation flag. Added test code for this to not happen in the future.
• Fixed a small bug with the checking of the MAX_FILE_LENGTH.
• Fixed a bug where if LOG_PNT_SEEN_COUNT was set to 0, dmalloc_examine would segfault if used.
• Fixed some problems with strndup and strdup argument checking.
