AFAICT these .stp files are generated from the source file "trace-events", so the keyword clash is not directly evident. (And it was likely authored by someone using a different tracing infrastructure.) > WARNING: tapset '/usr/share/systemtap/tapset/qemu-kvm.stp' has errors, and will be skipped. > WARNING: tapset '/usr/share/systemtap/tapset/qemu-system-i386.stp' has errors, and will be skipped. > WARNING: tapset '/usr/share/systemtap/tapset/qemu-system-x86_64.stp' has errors, and will be skipped. ... > Lots of warnings, although it seems otherwise unaffected.

Description of problem: Not sure if this is a qemu bug or a systemtap bug. Please feel to reassign. When you have qemu installed and you start 'stap' it prints lots of warnings: parse error: expected statement saw: keyword at /usr/share/systemtap/tapset/qemu-kvm.stp:1139:3 source: in = $arg3; ^ parse error: expected literal string or number saw: operator '=' at /usr/share/systemtap/tapset/qemu-kvm.stp:2078:8 source: next = $arg1; ^ 2 parse errors. WARNING: tapset '/usr/share/systemtap/tapset/qemu-kvm.stp' has errors, and will be skipped. parse error: expected statement saw: keyword at /usr/share/systemtap/tapset/qemu-system-i386.stp:1139:3 source: in = $arg3; ^ parse error: expected literal string or number saw: operator '=' at /usr/share/systemtap/tapset/qemu-system-i386.stp:2078:8 source: next = $arg1; ^ 2 parse errors.

Version-Release number of selected component (if applicable): qemu-kvm-1.0-11.fc17.x86_64 systemtap-1.7-5.fc17.x86_64 How reproducible: 100% Steps to Reproduce: 1. Run stap on any valid systemtap input file. 2. 3. Actual results: Lots of warnings, although it seems otherwise unaffected. Expected results: Shouldn't be any warnings. Additional info:
