[Raspberry Pi] Segmentation Fault on :build 0 (Finally..)
  
 
Posted: Mar 2, 2021

Two issues with version 11.1 Compiled for Raspberry Pi (armvl7):
1) Only responds with “Welcome”
2) “Build 0” causes Segmentation Fault
(TOPIC/ has github cloned BUILD0 and BUILD1 - same behavior if first clear TOPIC/)

Also happens on MacOS Big Sur on Mac mini 2018.  Submitted issue on github:

Managed to fix it.

1) Recompiled with symbols:  make clean debugserver
2) set ulimit -c unlimited to generate core file
3) Ran program from inside gdb (otherwise “no stack” if “gdb -c core, file ChatScriptDebug”):

$ gdb --args ChatScriptDebug local
(gdb) run
...
user7: :build 0
...
Program received signal SIGSEGV, Segmentation fault.
0x0017d388 in BugBacktrace (out=0x8a5a58) at os.cpp:1732
1732         if (frame->rule) strncpy(rule,frame->rule,50);
(gdb) where
#0  0x0017d388 in BugBacktrace (out=0x8a5a58) at os.cpp:1732
#1  0x0017f090 in BugLog (name=0x7eff0568 "LOGS/bugs.txt", folder=0x885fcc <logsfolder> "LOGS", bug=0x8a5a58, located=0x7efef9b0 "") at os.cpp:2153
#2  0x0017fb90 in Log (channel=10, fmt=0x26e2d8 "No such directory %s\r\n") at os.cpp:2330
#3  0x0017b98c in getdir (dir="VERIFY", files=std::vector of length 0, capacity 0) at os.cpp:1203
#4  0x0017bc18 in WalkDirectory (directory=0x26f6b8 "VERIFY", function=0x1b5e80 <EmptyVerify(char*, uint64)>, flags=0, recursive=false) at os.cpp:1307
...

(gdb) quit


mkdir ../VERIFY 

And the build succeeded.

And to fix issue 1 (for Raspberry Pi and Mac builds), “introduction keeps repeating” see:
