Bug ID: 26827
Summary: ld.gold --threads segfault since 2.35
Product: binutils
Version: 2.35
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gold
Assignee: ccoutant at gmail dot com
Reporter: nick.gasson at arm dot com
CC: ian at airs dot com
Target Milestone: ---
With latest binutils 2.35:
$ gcc -fuse-ld=gold -Wl,--threads test.c
malloc(): invalid next size (unsorted)
collect2: fatal error: ld terminated with signal 6 [Aborted], core dumped
compilation terminated.
$ gcc -fuse-ld=gold -Wl,--threads test.c
$ gcc -fuse-ld=gold -Wl,--threads test.c
double free or corruption (out)
collect2: fatal error: ld terminated with signal 11 [Segmentation fault], core
dumped
compilation terminated.
The contents of the .c file don't matter. I think it was introduced with
f37b21b481a7 PR 22843: ld, gold: Add --dependency-file option.
Simple fix:
--- a/gold/fileread.cc
+++ b/gold/fileread.cc
