            Bug ID: 29107
           Summary: gas testsuite parallel jobs fail (gprofng?)
           Product: binutils
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gas
          Assignee: unassigned at sourceware dot org
          Reporter: toolybird at tuta dot io
  Target Milestone: ---

** Please reassign this to gprofng if you believe the problem lies there **

I'm building binutils trunk on x86_64 and seeing testsuite failures in gas, but
only in the following circumstances:

 - gprofng is enabled
 - --enable shared
 - the whole binutils testsuite is run with parallel make jobs

Inside the log file the errors look like this:

exited abnormally with 1,
output:/build/binutils/src/binutils-build/binutils/.libs/lt-objdump: error
while loading shared libraries:
/build/binutils/src/binutils-build/opcodes/.libs/libopcodes-2.38.50.20220430.so:
file too short

/build/binutils/src/binutils-build/gas/.libs/lt-as-new: error while loading
shared libraries:
/build/binutils/src/binutils-build/opcodes/.libs/libopcodes-2.38.50.20220430.so:
invalid ELF header

Bisection (obviously) points to the introduction of gprofng.

Any thoughts? Thanks.


Steps to reproduce:

1. ../binutils-gdb/configure --prefix=/usr --with-system-zlib --enable-shared
--disable-{gdb,gdbserver,libbacktrace,libdecnumber,readline,sim}

2. make -j16 -O tooldir=/usr V=1

3. make -k -j16 -O check
