Bug ID: 30013
Summary: [2.40 regression] Assertion failed: one_type !=
two_type, file libctf/ctf-dedup.c, line 2342, function
sort_output_mapping
Product: binutils
Version: 2.40
Status: NEW
Severity: normal
Priority: P2
Component: libctf
Assignee: unassigned at sourceware dot org
Reporter: ro at gcc dot gnu.org

Target Milestone: ---
When I recently upgraded my self-compiled version used for gcc bootstraps from
2.39 to 2.40, a couple of testsuite regressions occured:
+FAIL: gcc.dg/debug/20020220-1.c -gctf (test for excess errors)
Excess errors:

They happen on Solaris/sparc and x86, 32 and 64-bit.
It turns out that the assertion failure occurs when qsort_r is missing from
libc
(as on Solaris 11.3, unlike Solaris 11.4).
However, there's nothing Solaris-specific here: if I disable qsort_r in
config.status on Linux/i686

(there sems to be no way to do this otherwise, e.g. by presetting autoconf
cache variables), I get exactly the same failure, so there seems to be
something
wrong with ctf-qsort_r.c.
