gecko/ArcticFox more GNU work - segmentation fault in python 2.7

[Riccardo Mottola]

Hi,

I decided to continue working on my ArcticFox efforts on hurd. I found 
this patch by Richard Braun:

https://bugzilla.mozilla.org/show_bug.cgi?id=1029809

Being ArcticFox codebase around FF 40-45, it was relatively easy to 
adapt&apply!

However, compilation halts with

62:47.37 In file included from ../../dist/include/nsTArray.h:2325,

sem_wait: Invalid argumentlibs tools
Segmentation fault (core dumped)

What did coredump and why? I found one core file and gdb tells me.


warning: Unexpected size of section `.reg2/4208' in core file.
Core was generated by `python2.7 ./mach build'.
Program terminated with signal SIGSEGV, Segmentation fault.


(gdb) bt
#0  0x0119c69c in ?? ()

The backtrace is not very helpful. I wonder if it is related with the 
invalid argument message on sem_wait ?

I tried relaunching build.. and it may either coredump again, but 
sometimes continues too
