Hi...
I have inserted some code for available analysis in the source code of
GCC4.0.2
But "make" fails at the file mf-runtime.c
the error i got is as follow:
/home/divya/GCC-4.0.2/build/gcc/xgcc -B/home/divya/GCC-4.0.2/build/gcc/
-B/home/divya/GCC-4.0.2/target/i686-pc-linux-gnu/bin/
-B/home/divya/GCC-4.0.2/target/i686-pc-linux-gnu/lib/ -isystem
/home/divya/GCC-4.0.2/target/i686-pc-linux-gnu/include -isystem
/home/divya/GCC-4.0.2/target/i686-pc-linux-gnu/sys-include -DHAVE_CONFIG_H
-I. -I../../../src/gcc-4.0.2/libmudflap -I. -Wall -ffunction-sections
-fdata-sections -O2 -g -O2 -MT mf-runtime.lo -MD -MP -MF
.deps/mf-runtime.Tpo -c ../../../src/gcc-4.0.2/libmudflap/mf-runtime.c
-fPIC -DPIC -o .libs/mf-runtime.o
../../../src/gcc-4.0.2/libmudflap/mf-runtime.c: In function
'__mf_sigusr1_respond':
../../../src/gcc-4.0.2/libmudflap/mf-runtime.c:2192: internal compiler
error: Segmentation fault
i tried to debug this code with gdb as follow:
# gdb /home/divya/GCC-4.0.2/build/gcc/xgcc
# set args -B/home/divya/GCC-4.0.2/target/i686-pc-linux-gnu/bin/
-B/home/divya/GCC-4.0.2/target/i686-pc-linux-gnu/lib/ -isystem
/home/divya/GCC-4.0.2/target/i686-pc-linux-gnu/include -isystem
/home/divya/GCC-4.0.2/target/i686-pc-linux-gnu/sys-include -DHAVE_CONFIG_H
-I. -I../../../src/gcc-4.0.2/libmudflap -I. -Wall -ffunction-sections
-fdata-sections -O2 -g -O2 -MT mf-runtime.lo -MD -MP -MF
.deps/mf-runtime.Tpo -c ../../../src/gcc-4.0.2/libmudflap/mf-runtime.c
-fPIC -DPIC -o .libs/mf-runtime.o
#run
Then segmentation fault message flashed by gdb was as follow:
Reading symbols from shared object read from target memory...done.
Loaded system supplied DSO at 0x833000
Detaching after fork from child process 26021.
../../../src/gcc-4.0.2/libmudflap/mf-runtime.c: In function
?__mf_sigusr1_respond?:
../../../src/gcc-4.0.2/libmudflap/mf-runtime.c:2192: internal compiler
error: Segmentation fault
What could be the possible reasons for such error??
