Bug ID: 65349
Summary: [5 Regression] go tool crashes, can't compile go code
on 32bit linux systems
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: go
Assignee: ian at airs dot com
Reporter: doko at gcc dot gnu.org
CC: cmang at google dot com
The go command didn't ship with earlier GCC versions, so you may argue that it
is not a regression, however a go command backported from 1.2.2 was able to
build code with 4.9 on at least arm-linux-gnueabihf, powerpc-linux-gnu and
i686-linux-gnu. Double-checked that the backported go command built with 5.0
shows the same failure. This seems to work on architectures like
aarch64-linux-gnu, powerpc64le-linux-gnu and x86_64-linux-gnu.
On these architectures I see for "go -v
on powerpc-linux-gnu (not on armhf and i386) building go-md2man

Log:
PR go/65349
runtime: Don't call malloc from __go_file_line callback.
When crashing, we call runtime_printcreatedby which calls
__go_file_line which used to call the Go malloc. If we are
crashing due to a signal due to heap corruption of some sort,
the GO malloc lock might already be held, leading to a crash
within a crash. Avoid that by assuming that the libbacktrace
strings will stick around, as we already do in go-callers.c.
