[Bug target/38642] New: [4.3/4.4 Regression] Code with -fPIC results in segfault on ARM (old ABI)

[tbm at cyrius dot com]

[ Forwarded from http://bugs.debian.org/487406 ]

Enrico Zini reported the following bug (with testcase) to Debian: the attached
code compiled with -fPIC results in a segfault on ARM (old ABI; not on EABI).

It works fine on other architectures or on ARM with gcc 4.2.

I verified that the bug is present in gcc 4.3 from SVN and in trunk.

only arm-eabi is in the list of primary/secondary targets.

Does this still occur on trunk ?

The bug occurs on OABI with gcc-4.3-20090705 but not with gcc-4.4-20090707.

This was fixed for 4.4 by revision 133117, which did a fair amount of stack
frame management changes. Applying that change to 4.3-20090712 fixes this test
case also for 4.3.

I'm not in a position to do a full regression test of an OABI toolchain, but I
may have time to test that it doesn't cause regressions for EABI.
