But I can still consistently repoduce ICE with the attached testcase (not fully reduced) gcc version 4.9.0 20131207 (experimental) [trunk revision 205782] (GCC) ~/gnu/gcc/trunk/arm-eabi/gcc$ ./xgcc -B. -Os ~/ice.i -c -g /home/ryan/ice.i: In function 'uDNS_ReceiveMsg': /home/ryan/ice.i:80:1: internal compiler error: in vt_expand_var_loc_chain, at var-tracking.c:8212 } ^ 0xbb0353 vt_expand_var_loc_chain ../../gcc/var-tracking.c:8212 0xbb0353 vt_expand_loc_callback ../../gcc/var-tracking.c:8408 0x64cef7 cselib_expand_value_rtx_1 ../../gcc/cselib.c:1684 0x64e31e cselib_expand_value_rtx_cb(rtx_def*, bitmap_head_def*, int, rtx_def* (*)(rtx_def*, bitmap_head_def*, int, void*), void*) ../../gcc/cselib.c:1531 0xbaf77a vt_expand_loc_callback ../../gcc/var-tracking.c:8344 0x64ce31 cselib_expand_value_rtx_1 ../../gcc/cselib.c:1649 0x64e31e cselib_expand_value_rtx_cb(rtx_def*, bitmap_head_def*, int, rtx_def* (*)(rtx_def*, bitmap_head_def*, int, void*), void*) ../../gcc/cselib.c:1531 0xbafc28 vt_expand_var_loc_chain ../../gcc/var-tracking.c:8246 0xbafc28 vt_expand_loc_callback ../../gcc/var-tracking.c:8408 0x64cef7 cselib_expand_value_rtx_1 ../../gcc/cselib.c:1684 0x64e31e cselib_expand_value_rtx_cb(rtx_def*, bitmap_head_def*, int, rtx_def* (*)(rtx_def*, bitmap_head_def*, int, void*), void*) ../../gcc/cselib.c:1531 0xba941c vt_expand_loc ../../gcc/var-tracking.c:8498 0xbbc0c3 emit_notes_in_bb ../../gcc/var-tracking.c:9094 0xbbc0c3 vt_emit_notes ../../gcc/var-tracking.c:9431 0xbbcb91 variable_tracking_main_1 ../../gcc/var-tracking.c:10292 0xbbcb91 variable_tracking_main ../../gcc/var-tracking.c:10306 0xbbcb91 execute ../../gcc/var-tracking.c:10347 Please submit a full bug report, with preprocessed source if appropriate.
