Bug ID: 103132
Summary: ice: Segmentation fault
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
For this C code:
int globus_i_GLOBUS_GRIDFTP_SERVER_debug_handle_1;
int globus_l_gfs_ipc_unpack_data__sz;
static void globus_l_gfs_ipc_unpack_cred(len) {
if (globus_i_GLOBUS_GRIDFTP_SERVER_debug_handle_1)
globus_i_GLOBUS_GRIDFTP_SERVER_debug_printf("", __func__);
}
static void globus_l_gfs_ipc_unpack_data(len) {
for (; globus_l_gfs_ipc_unpack_data__sz;)
len--;
len -= 4;
len -= 4;
globus_l_gfs_ipc_unpack_cred(len);
}
void globus_l_gfs_ipc_reply_read_body_cb() { globus_l_gfs_ipc_unpack_data(); }
compiled by recent gcc, does this:
$ /home/dcb/gcc/results.20211105/bin/gcc -g -O2 -c bug770.c
In function ‘globus_l_gfs_ipc_unpack_data.isra’:
cc1: internal compiler error: Segmentation fault

The fault first seems to occur sometime between git hash d3f7a2fa64f8777c
and bcf4065c909bd101, a distance of 25 commits.

ipa: Fix segfault when remapping debug_binds with expressions (PR 103132)
My initial implementation of the method
ipa_param_body_adjustments::remap_with_debug_expressions was based on
the assumption that if it was asked to remap an expression (as opposed
to a simple SSA_NAME), the expression would not contain an SSA_NAME
operand which is to be debug-reset. While that is true for when
called from ipa_param_body_adjustments::prepare_debug_expressions, it
turns out it is not true when invoked from remap_gimple_stmt in
tree-inline.c. This patch adds a simple logic to handle such cases
and simply map the entire value to NULL_TREE in those cases.
gcc/ChangeLog:
2021-11-08 Martin Jambor <mjambor@suse.cz>
PR ipa/103132
* ipa-param-manipulation.c (replace_with_mapped_expr): Early
return with error_mark_mode when part of expression is mapped to
NULL.
(ipa_param_body_adjustments::remap_with_debug_expressions): Set
mapped value to NULL if walk_tree returns error_mark_mode.
