Error(s) that match a know pattern in addition to what has been reported in the summary:


./configure: line 1685:    77 Segmentation fault      ".qconftemp/conf"
Reason: Unexpected error launching 'conf'

Do I understand correctly it's ARM-only issue? 
At least it build fine on my machine. But I'm on x86-64 and my software is a little outdated (gcc-13, qt-5.15.11)

If it's arm-only I don't really know how to test it. I hope ARM VMs work well on x86

tested on arm with gcc13 and glibc. no issue

Let's assume it's the same as bug 924237 for now. Please don't worry about it and I'll let you know if it ends up being a bug on its own.
