Subject: [Bug translator/2252] New: stap generated code does not compile on RHEL4 UP kernel
Reply-to: sourceware-bugzilla at sourceware dot org
When using a RHEL4 UP kernel on an i686 machine the code generated by the stap
translator does not compile. The problem is not observed with the RHEL4 SMP i686
kernel. This problem is doesn't happen on FC4 UP kernel either. This problem can
be observed on most all of the tests/testsuite/systemtap.base tests. 

The kernel:

$ uname -a
Linux slingshot.devel.redhat.com 2.6.9-27.EL #1 Tue Dec 20 19:13:33 EST 2005
i686 athlon i386 GNU/Linux

System version

$ /usr/local/bin/stap -V SystemTap translator/driver (version 0.5.3 built
2006-01-31)
