Hi there,

I compiled gawk-4.2.1 (with gmp-6.2.1 and mpfr-4.1.0) using musl-1.2.2.

Using it with I script I wrote I get

gawk: /.../.../build_total.awk:25: (FILENAME=big.report FNR=6) fatal error: internal error
./go: line 36: 14488 Aborted                 (core dumped)

Loading it into gdb doesn't give much information:

# gdb -q ./gawk core.gawk.0.51bcaa32ed144d2498e3a70ff28af961.14488.1632479605000000

(gdb)

I compiled gawk the same with regular gcc (version 8.3.1 20190507 (Red Hat 8.3.1-4)) into a dynamic binary with the same libraries, and that did complete my script without crashing.

Can anybody inform me how to find out exactly where the crash occurs and how I can help fix this bug?
