Status: RESOLVED DUPLICATE of bug 1710235

(Firefox Build System :: General, defect)

Description

[Ken Moffat]

Attachment: firefox89-ftbfs.log

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0

Steps to reproduce:

Tried to build 89.0b13 with gcc-11.1.0 and g++-11.1.0.

Actual results:

Failed to compile Unified_cpp_accessible_aom0.cpp.

0:43.89 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
0:43.89 319 | });
0:43.89 | ~~

Expected results:

I expected it to compile - some earlier 89.0betas compiled with gcc-10 and with clang-12.0.0.
