Built as above. I see a segv compressing InBuffer.o in build directory.
Program received signal SIGSEGV, Segmentation fault.
0x00024638 in NCompress::NLZMA::CEncoder::SetStreams (this=0x4158f000,
inStream=0x0, outStream=0x3, inSize=0x12, outSize=0x0)
at ../../../../../../src/sdk/7zip/Compress/LZMA/LZMAEncoder.cpp:1251
1251 RINOK(Create());
There is a problem with memory allocation in MyAlloc:
Breakpoint 2, MyAlloc (size=72355848) at ../../../src/sdk/Common/Alloc.cpp:24
24 if (size == 0)
This fails:
(gdb)
NBT4::CMatchFinderBinTree::Create (this=0x32100, historySize=8388608,
keepAddBufferBefore=<value optimized out>,
matchMaxLen=<value optimized out>, keepAddBufferAfter=419)
at ../../../../../../src/sdk/7zip/Compress/LZMA/../LZ/BinTree/BinTreeMain.h:97
97 if (_hash != 0)
(gdb)
101 return E_OUTOFMEMORY;
There isn't a check for out of memory at 1251, so segv. Don't have time
now to look at memory allocation problem.
