Re: fatal: internal error Ver 5.2.0 readall()

[Andrew J. Schorr]

Hi,

I'm seeing the same issue as OP on Linux CentOS 7 using the master branch:

bash-4.2$ ./gawk -l extension/.libs/rwarray.so -f /tmp/write.awk
writeall returns 1

bash-4.2$ ./gawk -l extension/.libs/rwarray.so -f /tmp/read.awk
arr1: len=0
readall returns 1
gawk: /tmp/read.awk:5: fatal: internal error: file interpret.h, line 253: 
unexpected parameter type Node_val

This sadly seems like a bug to me. If the code instantiates arr1 before
caling readall, then the saved arr1 in the state file sohuld be ignored
if all goes according to plan. I'm not sure I have time to troubleshoot
right now.

Regards,
Andy
