I'm getting the following segmentation fault:
Program received signal SIGSEGV, Segmentation fault.
0x000000000045e280 in netwk (cm=0x7f24d1a4f010, cmb=0x7f24d1a4f010,
cmc=0x7f24d1a4f010, cmd=0x7f24d1a4f010, ip=0x21b9a50, einc=0x21c7cf0) at
network.c:146
146 ipnt[irow1]= nseg1;
It is because ipnt has not been allocated. There's conditional code
that allocates this (and other structures) conditionally. If I make it
unconditional then all seems to work. However this patch, while it
works and works correctly is clearly not what the original author
intended. But I just don't understand why these variables would be
allocated conditionally.
Here's a patch that works (I'm sure the white space is murdered, sorry):
