8.130. ltrace
Updated ltrace packages that fix two bugs are now available for Red Hat Enterprise Linux 6.
The ltrace utility is a debugging program that runs a specified command until the command exits. While the command is executing, ltrace intercepts and records both the dynamic library calls called by the executed process and the signals received by the executed process. The ltrace utility can also intercept and print system calls executed by the process.
Bug Fixes
- BZ#868280
- Previously, the ltrace utility did not support the Position Independent Executables (PIE) binaries, which are linked similarly to shared libraries, and processes. Consequently, addresses found in images of those binaries needed additional adjustment for the actual address where the binary was loaded during the process startup. With this update, the support for the PIE binaries and processes has been added and ltrace now handles the additional processing for the PIE binaries correctly.
- BZ#891607
- When copying internal structures after cloning a process, the ltrace utility did not copy a string containing a path to an executable properly. This behavior led to errors in heap management and could cause ltrace to terminate unexpectedly. The underlying source code has been modified and ltrace now copies memory when cloning traced processes correctly.
Users of ltrace are advised to upgrade to these updated packages, which fix these bugs.
