Source: webkit2gtk
Version: 2.43.1-1
Severity: important
Tags: ftbfs experimental upstream
Forwarded: https://bugs.webkit.org/show_bug.cgi?id=266218

webkitgtk 2.43.2 (and 2.43.1) fails to build on Debian and Ubuntu's
riscv64 but seems to build ok on other architectures.

/Source/JavaScriptCore/offlineasm/riscv64.rb:132:in
`riscv64RaiseMismatchedOperands':
 Unable to match operands [RegisterID, RegisterID, LabelReference]
(due to LowLevelInterpreter64.asm:258) (LoweringError)

I have reported this issue to the webkitgtk developers.
