I have tried as I could to +#minimize the bug-causing program, so of course it does not seem to do +#anything useful in its present form. The error message received is: +# +#gawk: test.awk:15: fatal error: internal error +#Aborted +# +#Note that there is an attached file that the program reads, called "a". I +#played with the program a fair bit and my feeling is that the error is +#related with the delete statement, and not the reading of the file and the +#close statement. At one point I was able to remove the file reading and +#still obtain the error. If, for example, I remove the close statement and +#make two copies of the file instead, (reading one copy in sub1 and the +#other in sub2), the error still occurs. +# +#The operating system is Red Hat Linux, version 6.0, the gawk is version +#3.0.4, and the gawk was obtained from an rpm file gawk-3.0.4-1.i386.rpm. +# +#The program is: +# + +# Wed Mar 8 13:41:34 IST 2000 +# ADR: modified to use INPUT, so can set it from command line. +# When run, no output is produced, but it shouldn't core +# dump, either. +# +# The program bug is to not close the file in sub2. + +function sub1(x) { +# while (getline < "a" == 1) i++ + while (getline < INPUT == 1) i++ +# close("a") + close(INPUT) +} + +function sub2(x) { + i=0 + delete y +# while (getline < "a" == 1) z[++i] = $1 + while (getline < INPUT == 1) z[++i] = $1 + for(i in z) y[i] = x[i] + z[i] +} + +function sub3(x, y, z) { + sub2(x) + for(i=1; i<=4; i++) z[i] = y[i] +} + +BEGIN { + sub1(x) + sub2(x) + sub3(x, y, z) +} +# +#And the data file is: +# +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# 32.440 3.830 3.383700000000000 10.08 298 865 +# +# |
