Debugging with GDB Manual (5900-1473; WDB 6.2; January 2011)

export GDBRTC_CONFIG=./
export GDBRTC_CONFIG=/tmp
◦ Correct usage:
export GDBRTC_CONFIG=/tmp/yet_another_config
export GDBRTC_CONFIG=/tmp/rtcconfig
• BATCH_RTC enables or disables batch memory leak detection.
• On Itanium systems, from librtc version 6.1, gdb is not invoked in batch mode.
Prior to librtc version 6.1, the GDB_SERVER is used to override the default path from
where the gdb executable is used to provide the information on memory leak. By
default, /opt/langtools/bin/gdb is used to print the output. This can be
overridden by setting GDB_SERVER appropriately.
• RTC_MALLOC_CONFIG is used to override the default config and rtcconfig
file settings. This variable can be set as follows:
export RTC_MALLOC_CONFIG=config_string1[;config_strings].
◦ The config_strings are separated by a semi-colon(;).
◦ The following config_strings options exist for RTC_MALLOC_CONFIG:
Aborts execution when heap objects
bounds check fail, value is 1, and the
abort_on_bounds=[01]
environment variable RTC_NO_ABORT is
not set.
abort_on_bad_free=[01] Aborts execution when free or realloc is
trying to free a heap object which is not
valid, value is 1, and environment
variable RTC_NO_ABORT is not set.
abort_on_nomem=[01] Aborts execution when out of memory if
value is 1, and environment variable
RTC_NO_ABORT is not set.
leak_logfile=stderr[+]filename The log file for batch mode must be
specified.
stderr: error message goes to stderr
[+]filename: error message goes to
filename, + means output is appended to
the file.
