Bug#960242: mozjs68 FTBFS with ICU 67.1

[László Böszörményi (GCS)]

Source: mozjs68
Severity: normal
Justification: fails to build from source (but built successfully in the past)
Tags: ftbfs

Hi,

Soon the ICU transition will start. Your package FTBFS with the ICU
67.1 version, currently in experimental. Strange that the build
failure doesn't look like related to ICU (relevant lines hopefully):

Do you have any pointers?
