[Bug translator/3232] New: unable to allocate memory for context on rawhide x86_64

["wcohen at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

When trying to run the "make installcheck" tests on a updated x86_64 rawhide/fc6
machine many of the tests fail, even simple ones like
src/testsuite/systemtap.base/add.stp.

 ./stap -k -vv
/home/wcohen/stap_testing_200609201420/src/testsuite/systemtap.base/add.stp

towards the end gives the following error message


Running sudo
/home/wcohen/stap_testing_200609201420/install/libexec/systemtap/stpd -u wcohen
-d 25459 /tmp/stap4llS8n/stap_25459.ko
insmod: error inserting '/tmp/stap4llS8n/stap_25459.ko': -1 Cannot allocate memory

Doing a narrows the problem down to something that change between september 18
and september 19:

20060914 Worked
20060918 Worked /tmp/stapCto3iJ/stap_26001.c
20060919 Failed /tmp/stapLIgdOB/stap_26093.c
20060920 Failed

There do not seem to be obvious differences between the .c files used to
generate the modules that would cause a problem. However, the problem seems to
follow the compile module, .ko:


$ sudo /home/wcohen/stap_testing_200609180830/install/libexec/systemtap/stpd -u
wcohen -d 26455 /tmp/stapCto3iJ/stap_26001.ko
systemtap starting probe
systemtap ending probe
systemtap test success
$ sudo /home/wcohen/stap_testing_200609180830/install/libexec/systemtap/stpd -u
wcohen -d 26455 /tmp/stapLIgdOB/stap_26093.ko
insmod: error inserting '/tmp/stapLIgdOB/stap_26093.ko': -1 Cannot allocate memory
ERROR, couldn't insmod probe module /tmp/stapLIgdOB/stap_26093.ko
