Bug ID: 116865
Summary: ICE when compiling GNU coreutils numfmt with
-fanalyzer
Product: gcc
Version: 14.2.1
Status: UNCONFIRMED
Keywords: ice-checking
Severity: normal
Priority: P3
Component: analyzer

Compile with "gcc -O2 -S -fanalyzer t.i" to get internal compiler error
This is gcc (GCC) 14.2.1 20240912 (Red Hat 14.2.1-3) on x86-64. I don't see a
problem with gcc-13 on Ubuntu so I guess it is a regression.
Decompress and compile the attached program with:
gunzip t.i.gz
gcc -O2 -S -fanalyzer t.i
The output is:
during IPA pass: analyzer
src/numfmt.c: In function ‘unit_to_umax’:
src/numfmt.c:843:53: internal compiler error: in build2, at tree.cc:5093
843 | if (*end == 'i' && 2 <= n_len && ! c_isdigit (*(end - 1)))
